Thank you for the kind words. Interestingly, had you not included that you’ve been to Costa Rica, I’d say that was the obvious suggestion because they really do that sort of thing well and it’s at least a bit better organized than its neighbors. And if you were less concerned over travel time, I’d have some interesting suggestions for you in Asia. However, as you know, it takes nearly a full day just to get to Asia from the US or Canada, and then a few days to adjust, so you might be best off saving that for later.
As Christmas approaches the city will fill up much more, so if you can go early in the month you'll be much better off. But even if you can't go before the last week of the month you'll still find Mexico City to be a tremendous bargain compared to pretty much anywhere else in North America. It's a great shopping destination, and not just for goofy souvenirs, so that's something to think about as well.
From Atlanta, the places that come to mind with the theme of “nature” would be Costa Rica and Belize. Costa Rica is probably the better choice, as it famously has around a third of its land as natural parks. Much of it is jungle, and they have all sorts of activities including zip lining, but also canopy tours and much more. There is also the Arenal volcano there, which is really nice and has some fun hot springs around it. They also have beaches, of course, but there is plenty in the interior of the island to keep you busy. If you know a bit of Spanish, it helps, but most other visitors know little or none.
I’ll be happy to give you some suggestions, but it would really help to know your starting point and approximate budget. At this moment I am writing this reply from Cancun, which could be perfect if you are in or near the US, but if you are in another part of the world there will likely be better choices. Although thinking about it, even if you are in Europe, a place like Cancun might still be best. Let me know and I’ll give you my best answer and an alternative or two. -Roger
As for alternatives, you might have a look at my recent article with my recommendations for the best places to go in Asia in December. It’s got many more choices than the article above, with weather information for all of them. Closer to India, I think Sri Lanka is very nice in December, although it’s somewhat similar to India in many ways and you may want something more exotic. In that case I think Thailand and Malaysia are the best choices for family holidays.
It’s unfortunate and heartbreaking how many times I have recommended San Juan, Puerto Rico in the last few years. Once they get the power back on I’m sure it’ll be back to normal fairly soon after that, but I’m guessing probably March or later. And fortunately, Nate missed the Cancun area for the most part. Have you considered somewhere in the Cancun/Playa del Carmen/Cozumel area? I’m particularly fond of Playa del Carmen, and that flight to Cancun should be pretty reasonable for you.
Vacationing to Sicily during Italy’s traditional “off-season” has been trending in recent years, according to American Express Travel. What gives? Well, for starters there's Sicily's fabulous Mediterranean setting, as well as its rich baroque aesthetic and festive Catholic traditions. Plus, the crowds are more manageable than they are in the summer, which makes travel for families and large groups a breeze.
