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.”
Keep Snacks Handy When You are Out – This was my snack stash for Disney World. I had Macadamia Nuts, Walnuts, Pecans, and low carb bars. I made sure to chill the water bottles in the freezer beforehand so that as they thawed throughout the day, we had cold water. When hunger hit, instead of falling to temptation, I just grabbed my bag of snacks before I got HANGRY. Doing so made it so much easier to make keto/low carb choices at mealtime. I kept my snacks simple because we already had enough to bring with us (if you have a baby and a toddler you know what I mean). I saw lots of people with small coolers who were snacking on fresh veggies and deli meats, but, again, my goal was easy breezy. You can find a great list of Keto/Low Carb Snack ideas here for inspiration if you prefer a variety.
My top recommendation would be San Juan, Puerto Rico. It offers a wonderful mix of history and culture and nightlife and great food, alongside excellent beaches and abundant activities. Hotels and rental apartments are mostly in the mid-range for the Caribbean, but food and drinks and most other things are great value. You could get a place in the Condado area, which is close to the lovely Old San Juan neighborhood and plenty of nightlife all around. And then perhaps you could rent a car and stay for a few days at one of the smaller beach towns elsewhere on the island. You wouldn’t even need a passport, although it does feel fairly exotic while you are there. But because it’s part of the US, it’s also well organized and safe. Most people you’ll meet will speak at least some English, and many are fluent, so it’s easy even if you don’t speak Spanish.
In Rome, the Coliseum and Ancient Rome are outdoors, but the city also doesn’t get as cold as the others so most likely you’ll be fine if you bundle up a bit. In Venice, they often have those floods during December, but they come and go every 6 hours so even if you get unlucky you’ll still be able to get around half the day, and it’s a small city anyway.
If I were you I’d fly to Bangkok and stay at least 2 or 3 nights in the famous Khosan Road area, which has a bad reputation with some people, but it’s really fun. It’s also cheap, and a short walk from most of the main cultural sights. After that you could fly to Ko Samui or Ko Phagnan or Ko Phi Phi, and easily find the better party spots. You could also go to Phuket, but I prefer the others for younger people. Phuket has loads of nice beaches for families and couples, but the one “party town” (Patong Beach) is a bit over the top, and mostly geared for groups of men who want to go to the “beer bars” and strip clubs and whatnot. The smaller islands will have a more mixed crowd, including many backpacking females. Hopefully this helps. Let me know if you have any other questions. -Roger
My other two suggestions are San Juan, Puerto Rico and Cartagena, Colombia. Both cities have really wonderful colonial districts and modern resort districts nearby. San Juan is more expensive, but still reasonable, and it has far better beaches. Both have a bit of rain in November, but it tends to come and go quickly. You’ll get similar rainstorms in most of the Caribbean in November, so it’s a bit tricky. I hope this helps. If you had something else in mind let me know and I’ll try again. -Roger
New Zealand will also be crowded, but the country is otherwise mostly empty so it is still wonderful. You could fly to Auckland for one day or so and rent a campervan/motorhome. Drive it for 3 or so days on the North Island, and then onto the ferry to the South Island for the rest of your time. The South Island is far more scenic and less crowded. You’ll be doing some driving and looking, but after a few hours of that you can stop at a campground and have plenty of things to do such as hiking or water sports and much more.
