B H,
I say go and enjoy yourself. I travel a lot with the military and for pleasure and I find that my colon loves to be outside the US. I recently went to Serbia for a month and ate on the local economy and have never felt better. A week later I went to the Dominican on vacation and ate resort food. I felt great there too, and was even drinking quite a bit (since it was all-inclusive). I stay away from my trigger foods as usual, but I always try the local cuisine wherever I go for the experience. Many times I have been in a flare and gone on a trip and came home feeling great. I try not to worry about it since I never really know where I am going and what I am going to eat, and it seems to turn out well.
Have a great vacation!
