Two of the easier other choices would be London or Madrid. From Amsterdam you can take a train to Brussels and then change for the Eurostar train to London, or you can fly. From London to Barcelona you’d want to fly for sure. If you chose Madrid you can go to Amsterdam and then fly to Barcelona and then take a train from Barcelona to Madrid in only 2.5 hours.
It would be hard to beat Chiang Mai for its combination of great November weather and low prices. Even though it's officially the start of the high season for hotels, the beginning of the month is usually very slow anyway, so bargains are common. Hotels in Chiang Mai are among the best bargains in the entire world, so even if you do have to pay full price for a room it'll be cheaper than a dorm bed in most European cities.
Take Meal Times in Stride – Although I had intentions of planning keto/low carb meals by researching restaurants beforehand, especially at Disney, that never happened. Did I mention I have four kids? Yea, I don’t have a lot of downtime. Even so, I never had any problem finding foods that I could eat at restaurants. When we were out and about in Orlando, if we were thinking about eating at a restaurant that I hadn’t eaten at before, I looked their menu up online in the car before walking in. As long as they had a keto/low carb option, it was a go. I wasn’t picky. In fact, I ate either a bunless burger or bunless grilled chicken club almost every day at Disney or Universal. When my kids wanted to order pizza one night at our condo, I ate the toppings off with a fork. When they wanted Mexican food, I enjoyed Chicken Fajitas on a bed of lettuce. Whatever my family wanted, I found a way to make it work, and I never felt deprived. We typically ate breakfast at our condo, a late lunch (at Disney or Universal if it was a park day), then a late dinner out. By doing so, we also saved a great deal of money since eating inside the park can be so expensive. Since we stayed off site, the dining plan wasn’t an option.
Needless to say, Australia is a huge country so you could spend 6 months there and not get bored, or you could spend one week there and barely see any of it. The obvious destinations are Sydney and Melbourne, both with plenty to do for non-beach people. Melbourne is known a bit more for culture and food, while Sydney is more pleasant and still very interesting. There is also the Great Ocean Road, which is a very scenic drive just a bit south of Melbourne.
Thank you, and I’ll be happy to try to help. But first I have to mention that ALL of Europe is quite cold in December and there are no beaches that are anywhere near warm enough to even spend time on, much less go swimming. The only place that could possibly fit the bill is the Canary Islands, which is off the northern coast of Africa although technically part of Spain. It’s reasonably warm there during December, and there is quite a bit to do.
Increasingly popular, Lisbon is quite warm in summer, but November’s cooler temperatures and fewer crowds make it a pleasant time to visit. A city of hills and spectacular views, many terraces (miradouros) offer vistas for those who climb (or take a taxi) to the top. Alfama is the city’s historic district, defined by hilly, narrow cobblestone streets. The Fado Museum, in Alfama, honors Portugal’s soulful folk music and provides some background on the sounds heard nightly in the city’s fado houses and bars. Seafood is plentiful in Lisbon, and the traditional Portuguese dried salted cod (bacalhau) is on most menus along with octopus, shrimp, sardines, clams, and tuna.
For the record, the official Hurricane Season runs from June 1 to November 30, but hurricanes in November are extremely rare, so we have likely seen the last of them for this season. The devastated islands will need help rebuilding, and the remaining islands are hoping that visitors know they need the business as well, and that there is no risk of big storms starting in December and usually earlier. -Roger
With a vibrant downtown, great restaurants, culture, and a recent multi-million renovation to the Ritz Carlton, Naples, one of the areas most luxurious hotels, December is when the town really starts to get into gear. You can spend your time on the miles of gorgeous Gulf Coast white sand beaches, take an Everglades Safari, or head to the Artis-Naples which hosts world class dance, theatre, music, and comedy. And that is to say nothing of the five-star shopping.
Mauritius would be an interesting option if you wanted to mainly stay in one place, which I think is typical on a honeymoon. Sri Lanka is fascinating and really nice, though most people who visit tend to tour around seeing some beach areas and some of the hills and jungles. So I’m not sure if it’s ideal if you want to just stay in one place. Kerala has some really nice resorts that are within easy reach of the backwater boat tours and other attractions.
Vietnam might be your best choice of the three. Most people (if they can) fly into Hanoi and fly out of Ho Chi Minh City (Saigon) or the other way around. Again, you can travel between them by train, although getting tickets can be a bit complicated. Hanoi is really interesting and nice (and super cheap). The best tourist city in Vietnam is Hoi An, which is between the two big cities. There’s a nice beach there and a bit farther away is Denang, which has large resorts along an excellent beach. Nha Trang is another good beach city in Vietnam, but probably not great for families. Ho Chi Minh City is bigger and more crowded than Saigon, but it’s also more modern (and hotter). You could spend two really nice weeks going north to south in Vietnam with a long stop in Hoi An.
Being from Mumbai you can be forgiven for not realizing how unappealing beach areas are when the air temperatures are only a bit above freezing. Seriously, even beach on the European mainland is totally deserted by November 1, and many of the local hotels and restaurants are closed by then until April or so. Now, if you are mainly after the novelty of being on a beach in the European winter, you can certainly go and still find open hotels and restaurants. If I had to recommend one place to consider it would be Spain’s Costa del Sol, which is the resort area around Malaga. The average high in December in Malaga is 17, and the average low is 8. You’d be the only one on the beach, which might be kind of nice. It’ll also probably be windy. If you were going to do that I’d recommend staying in Malaga itself, which does have a nice beach area in the city, and since it’s a city the hotels and restaurants will all be going.
The park we visited has an app you can download on your phone that allows you to reserve a table at any table service restaurant on their property ahead of time. The app also lists the daily breakfast, lunch, and dinner offerings at every single food establishment on site. There really is no excuse for settling for the popcorn or french fries when you can easily find a place with compliant options if you’re willing to look and tweak a bit. A lot of other theme parks are either offering similar apps or putting their information online for those who need to research their options ahead of time. If your destination is the beach or a famous city, check out what’s in the area online, or call your hotel to get an idea.
If you are more interested in nature and adventure than culture, then the top choice would be Costa Rica. The country has many beautiful national parks and it’s filled with things like zip-lining and canopy tours, just to name a few things. There are also volcanoes and surfing beaches and much more, plus a very good backpacker infrastructure of cheaper hotels and hostels.
Hotel prices definitely go up in around Christmas so it's best to come early in the month if that's possible, but it's still a pretty good bargain even during the peak weeks. Book early if you can because the better and cheaper hotels will fill up first, of course. Also consider a side trip to the Mendoza wine region, Patagonia, or the amazing water falls of Iguazu.
As for Europe, it’s the low season there at the end of the year and you might be able to find a reasonable flight. Have a look at my list of best Europe destinations in December for weather and comments about each of the better places. If money is tight then Europe can be challenging because getting from place to place can add quite a bit to the daily total. I think two weeks in Spain and Portugal could be very nice, with reasonable weather and relatively low prices. Let me know what you think and I can try to help you more. -Roger
