I'm a fellow Atkins follower. This upcoming trip in April will be my third trip to Disney while on Atkins. Although you can easily make low carb dining choices and find a variety of options, I opt to not follow the plan while on vacation. What's a vacation without the good food that comes along with it? Now I don't pig out on it do to my appetite being surpressed anyways since on the plan for so long, but I do eat regular food, don't do soda except diet, but I'm guilty of taking advantage of the sweets, lol!! I have tried to follow it while on vacation, but decided against it, I just wanted to have a more relaxed vacation, and be able to do the character meals with my family. For instance when we do a Character Breakfast, If i followed the plan the only thing I can pretty much eat is bacon and eggs and I can't justify spending $18 on bacon and eggs, same with any Disney Buffet we go to. So if you plan to follow the plan while down there I would stay away from buffet meals. I am not trying to encourage you to not follow the plan, it's just my personal decision not to. Also wanna add, that the day we arrive back at home, I am back on the Plan. When I weigh myself after i've been off the plan for vacation, I find that I don't gain or loose a pound, so going off the plan for vacation is'nt a bad thing for me since I mantain the same weight as when I left, I think all the walking and sweating pays a huge part in that. Be sure to drink lots of water while down there too, vs diet soda, etc. Goodluck and have a great time.
Another thing, I would take along some Atkins Bars for snacks. This way if other people in your party stop for ice cream, dessert, etc, you will have a bar to eat.
