I had some great workouts in Disney World about two years ago. Keep this in mind:
Your NEPA is going to be out of this world. You'll walk miles and miles and miles and miles. You're going to burn a lot of calories, and most people would have a tough time gaining fat, even if their diets were a little crazy. So, no need to do any specific cardio!
What I suggest is to hit the iron hard before you go, maybe over-reach a little so you'll need the break the following week. Then, at Disney World, do some bodyweight stuff, not training to failure. I found a little playground area where I stayed and did push-ups, pull-ups, BW jump squats, stretched a lot, etc. I also took along two bands and one gripper, and played around with those.
I packed a tub of protein and some oatmeal too. Lowered the cost of Disney food and helped me keep the nutrition up. I had one oatmeal shake for breakfast and one plain protein shake as my last meal of the day. Usually enjoyed a big buffet halfway through the day.
Anyway, it was a nice break, my body needed the active recovery, and I was rejuvenated for the iron when I came back. So that's what I'd suggest for you. Grope Cinderella for me.
