snacks, breakfast stuff, peanut butter & jelly, the kitchen sink...
1st trip I read up on people bringing food down there because everyone said how expensive food at Disney was, and I bought into it. Never again... no one ate the snacks because we were too busy eating mickey ice cream, turkey legs, etc etc at the parks. No one wanted pb&j because we were too busy trying out all the new food items there. No one wanted to eat breakfast in the room because the danishes and muffins were so much better. All that food I had lugged to FL had to come right back to OH.
Another thing I would never take back down is a backpack. Too heavy, too big, too annoying at bag check. Nope... in our case less = more. Fanny pack, small messenger bag... that's it.
Not gonna bring down beach towels either, no siree no.
