I'm pooh sized (as it's called here) and when we went in January (no free dining) I gained a few pounds. I've lost about 40 pounds in the last year, but when I go on vacation I gain(no matter where). While walking all day, not the same as exercising at home. On top of that, I eat more snacks. I eat the same breakfast and dinner but add more at lunch and at night. Plus I like to drink while on vacation so that doesn't help.
