I’m sure you’ll have a great time. I don’t have any good suggestions for where to celebrate Christmas, but I’m sure you’ll have no problems finding something by just walking around or checking online. The top draw in Barcelona is the architecture, and especially the 20th Century buildings by Gaudi. I recommend the hop-on, hop-off bus tour because it allows you to see almost all of the famous buildings from the street in just a few hours. Park Guell is worth a visit, but of course the main attraction is the Sagrada Familia cathedral. Check opening times and reserve a ticket in advance if you can.
However, I also happen to be an athlete and about a month ago I reached the point where I had almost no power, no energy, constant hunger (and “hanger”) and cravings for practically anything bad like alcohol, sweets, carbs, artificial sweeteners or energy drinks. I tried to fight it. I started over multiple times. At one point I just couldn’t stick to any sensible dietary routine for longer than a day or two. Intermittent fasting, OMAD (one meal a day), TMAD (two meals a day) and keto all seemed to stop working.
Sri Lanka doesn’t really have a good infrastructure for budget travelers at this point. There are loads of nice hotels if you are willing to pay US$40 or more per night, but almost nothing below that except for a few hostels. I haven’t been to Palawan but I have been to Boracay and Palawan can’t be too much cheaper. Boracay doesn’t have many budget options either, so my guess is that Thailand or Cambodia is your best bet.
Another consideration is that Thailand is generally easier to get to with far more flights that are often cheaper, and Thailand also has FAR more beach options because of its long southern coastline and especially the islands. The posh beach areas on Phuket are typically the most expensive beach hotels in Thailand, but there are other more remote beaches in Phuket with lower prices so it’s worth a look. Aside from Phuket you should also look at Ko Samui, Ko Pha Ngan, and Ko Phi Phi. You might also look at the town of Pattaya, which is the closest beach resort to the Bangkok Airport. Parts of town have a lot of single foreign men in certain bars at night, but most of the town is actually quite family friendly and very good value. Let me know if you have other questions. -Roger
Vietnam might fit the bill for what you are looking for. The most popular itineraries are to start in Hanoi and end up in Ho Chi Minh City, or the other way around. There is a nice train connecting them that is scenic in many places, and the best must-stop place in between them is Hoi An. You also don’t want to miss Halong Bay, which is just outside Hanoi. Vietnam mostly attracts cultural travelers rather than party people. The food is excellent (France used to run the place) and there is plenty of culture all around, in addition to some nice beaches in Nha Trang and Da Nang (next to Hoi An).
Oh, and I just noticed you asked about general safety as well. Buenos Aires is fine as long as you don’t wander into the bad neighborhoods after dark, which is pretty much true almost anywhere you go, including Europe. But Rio is sadly famous for petty crime and it’s a real issue. As long as you know what NOT to do it’s quite safe, so I’ll still recommend it as long as you read up a bit on the topic. The most common problem is when people walk down to the water on the beach after dark. As long as you know NOT to do that you should be fine, but if you did go for an evening walk near the water and out of sight of the well-lit sidewalks, the chances of getting mugged are extremely high. Again, it’s worth learning about it and it’s easy to stay safe if you do. Let me know if you have any other questions. -Roger
Visit the Bahia Palace and gardens with its intricate artisan details. An overnight train ride north would bring you to the Moroccan seaport city of Tangier, once the playground for the rich and famous, celebrities, and artists. Admire the unique architectural and culinary influences from Spain, Portugal, France and Northern Africa as well as panoramic views of the city and bay from the hilltop Kasbah. The Musée la Kasbah is fascinating, and Café Hafa is a wonderful stop to quench your thirst and rest your feet. Visitors should visit Cape Spartel and the Caves of Hercules for its incredible history and captivating scenery. Perhaps a camel ride on a sandy beach or through the desert is your thing? Your Moroccan excursion is guaranteed to cover all bases from exotic to adventurous to mystical.
While the Caribbean destination tends to overflow with families during the holidays in December, go a month earlier and you’ll be treated to sunny days sans screaming kids, plus less expensive airfare. “November is my one my favorite months. The hustle and bustle of high season hasn't kicked in, average temperatures are in the 80’s, and the water temperature is lovely,” says Michael King-Hew, the proprietor of Kamalame Cay, a private island resort in the Bahamas. King-Hew specifically suggests for the resort's annual wellness retreat. “It’s the perfect way to get rested and in shape before the start of the hectic holiday season.”
There's a massive range of quality and prices when it comes to hotels in Bangkok, and the city is enormous as well, so you really want to do your research for this place. Most people are happier paying a bit more to stay near the river and all the tourist attractions, or even in the infamous Khosan Road backpacker district, which is cheap and fun, if tacky.
Cartagena is a lovely place as well, but another reader just pointed out that the US government has a new travel warning to all of Colombia as of June, 2017. The US has travel warnings to many countries that people still safely travel to every day, but it is something to consider. Many years ago Colombia had quite a few problems, and yet Cartagena was always okay because it is this little cruise port and tourist city far away from the major urban centers. Seeing this, I would think twice myself, although I wouldn’t rule it out, but I also wouldn’t go anywhere except Cartagena at the moment.
This is a difficult question to answer without quite a bit more information. First off, it’s obviously going to be pretty cold in most of Europe that time of year, although most of the major cities aren’t known for accumulations of snow. As long as you are okay with cold weather then it’s mostly down to budget and your main interests. I’m guessing that you haven’t been to Europe yet since you didn’t mention any places that you’d prefer to skip this time.
In November you can find excellent resort deals all over the Dominican Republic, but Punta Cana is typically the first choice, especially if you are looking for an all-inclusive resort with all the luxury extras at a great price. The resort is actually a collection of little beach areas on the eastern tip of the island, so it's very secluded and well away from some of the confusion closer to the capital city.
If you have a budget that allows at least US$300 per night, you should be able to rent a nice condo in Hawaii. If you haven’t been there before, it’s worth knowing that each of the 4 main tourist islands is quite different from each other, and only Oahu has an urban center that should probably be avoided. You’ll want to rent a car as well, as getting around is difficult without one.
Thailand is far more different and it’s easier to get around. The tourist areas are quite modern and well organized, and enough people speak English that it’s easy to do whatever you like. Again there you have choices of cooler areas in the north such as Chiang Mai, and of course Bangkok, as well as all of the islands. Let me know if you have any questions. -Roger
If you are very sensitive to humidity (I normally am, to be honest) then you’ll find more pleasant weather pretty much anywhere else in Southeast Asia in December. It can actually be cool at night in places like Chiang Mai that month. On the other hand, I LOVE Bali and I’ll probably spend all of next February there, which is still in the wet season. I’d still seriously think about Bali if I were you.
Aside from Indonesia you might also consider Thailand, which has great infrastructure so it’s much easier to travel with young children. Phuket has by far the most options, and its rainy season usually ends in early November. For families I recommend Kata Beach and Karon Beach, which are both just south of the main shopping and nightlife town of Patong Beach.
A charming, historic city to visit any time of year, Edinburgh is especially festive during December. Walking through its cobblestone streets takes you back to medieval days when sheep, cattle, and grain were sold in what is now the center of the city. Today, the Royal Mile includes shops, cafes, and museums. Edinburgh Castle, a must for first-time visitors, dates to the 12th century, with its dramatic silhouette overlooking the city. For those seeking holiday celebrations, the Royal Botanic Garden is decorated with lights, music, and illuminated trees. European-style Christmas markets pop up at Princes Street Gardens and George Street, offering traditional crafts, gifts, food, and warming drinks, most welcome during chilly December. The annual Hogmanay celebration welcomes the New Year with fireworks, food, and festivities. Don’t miss the delicious and ubiquitous fish chowder called “Cullen skink,” and be sure to try haggis, served with “neeps and tatties” — mashed turnips and potatoes. Buttery shortbread and whisky from the country’s more than 100 distilleries are also Scottish specialties. A stay at the elegant and historic Balmoral Hotel will enhance any visit to Edinburgh, and while you’re there, you’ll notice that Scottish actor Sean Connery was a guest, as was J. K. Rowling who finished the last Harry Potter book in one of its suites.
If those flights are too expensive you might think about going somewhere else in Mexico or to Costa Rica. The area around Cancun including Playa del Carmen and Tulum and Cozumel has a LOT going on. And if you’ve been there you could instead go to the Puerto Vallarta area, which is very different and also great. For activities though it’s hard to beat Costa Rica. I think they invented zip-lining and the country is about one-third national parks with all kinds of fun activities. Let me know if you have any other questions. -Roger
