Tom is pretty diligent at updating it on a regular basis (he's at
Disneyland now getting the latest info).
Tell him to get French Market updated; it's been wrong since October!
Besides the calories and the weight gain, I find that I can't handle a few days of fatty, salty foods -- my body isn't used to that and I end up feeling icky.
It's so true. Once you get used to eating better, it just feels gross to eat the old way after a few days.
Water water water!
Budget for fruit!

Have a PLAN for when you get home!!!!! This, in my experience, is the MOST important one. Even if you end up going wild at Disney, the important thing is getting right back into your plan at home. So if you have NO food at home when you get back, you'll probably end up going out to eat, or picking up a pizza, or other things that aren't the absolute best at getting you back on track. (not that there's anything wrong with either of those things...we go out to eat and we get pizza about once every two weeks, but it's probably not THE best way to get on track when you get home) So have a couple nice options at home in the freezer (or fridge if it's a really short trip), have a PLAN, and do the plan.
We had a longer trip and we ended up having two WW weigh ins during the trip (I can't remember the actual location, but it's basically sort of off the same road as Trader Joes and
Best Buy and that big mall, it's a nice location!). The first Saturday morning meeting, I had lost a few pounds. The second one, after a full week of Disney eating, I was up over 5.

The employee there was aghast and didn't want to say anything out loud, and I was cracking up when I looked at my card. I mean, come on, did she really think I had gained 5 lbs of FAT in a week?
If I'd let that derail me, well, it wouldn't have been good. But I was realistic about it, I knew it wasn't really fat, but if I kept on eating like crazy once home it could have ended up being a true gain. So I just went back to my plan once home, and it was gone, plus more, in 2 weeks.
We have a 2 week Florida trip coming up...you can bet I'll have a plan for getting home after that!
Oh, and I have enjoyed wearing my heart rate monitor to calculate calories burned while in the parks. I'm routinely over 2000 calories burned by afternoon. Wow!
