Yes I did it, just booked a new trip - a 13 day tour in Costa Rica with Gadventures in December.
I have been thinking about travelling around christmas/new year, but been so slow on deciding. It is great being able to travel at that time, you can stay away for a while without taking to many days off work. Last year I spent new years in Tokyo and the year before I was on a trip in Vietnam and Cambodia at that time. But I have never traveled during Christmas before and that was a limit for me, I love spending Christmas at home...
But this trip was so tempting so I just did it. Leaving December 19th, going home January 1st. And just take a look at what I will be doing: Costa Rica Active Adventure. I've been on one of Gadventures active trips before, in Peru, best holiday ever.
This is the route:
