OK, I'll be honest.
I weighed myself 12/22. I ate, shall we say, "heartily" over Christmas Eve, Christmas Day, and I left 12/26 for an 11 day WDW vacation, including a 4 day
DCL Cruise. I got back to Curves on 1/16. I weighed 9 lbs more.

To be fair I didn't really diet the week between my return from WDW and my return to Curves.
However, since then, I've lost 10.5 lbs, so I'm back on track now. I think alcohol also plays a part because on the cruise I had several mixed drinks a day, including creamy ones like pina coladas and konk koolers.

Avoiding alcohol would have probably cut my gains by a few lbs (so would have getting back on track the day I got back to NJ)
I would say, calculate your activity points in with what you eat. Make an effort to walk, to swim, etc. You will likely be burning up a lot of calories. I agree with the point about filling up on salads and veggies and making an effort not to eat too late at night. Also, eat slowly and enjoy your food. Don't deny yourself something you really want, but pay attention to what you're eating. Imagine your hunger on a scale from 1-10, 10 being starving in a desert with no food for weeks and 1 being completely full without room for a bite, overstuffed. You should eat before you get to a three and stop eating when you get to a 6. Don't eat past the point of a six- comfortably full, but you "could" eat a little more. I'll try to do this next time.

Just remember it will take you at least as long as it took you to gain it to lose it. I ate for 3 weeks to gain it and it took me 5 weeks to take it off.
I guess if you're going for a week, you can just enjoy it and diet at home for a week or two. If you're going for three weeks, take a lesson from me, and don't let it go too far like I did. And another point- the longer you eat "off plan" the harder it is to get back on track- thus my *additional* week of dietary indiscretions.
I don't know if any of this helped, but that's my $0.02.
