I have 20 days (gulp!) before my surgery, but only 16 before I fly out of here.

Trying to think of something fun to do with my kids that I won't be able to do afterwards. Thinking of things like water park, amusement park, movies (well, those I can do!), beach, etc.
What do y'all suggest?
I'm almost packed.
My biggest worry? Not the surgery (though yeah, I want it over with and I want to be awake!). It's the food. I won't have my usual foods. That's what scares me. Unfamiliar food in an unfamiliar country. Ok, I'm weird.
