Hey.. I want in on this great challenge

I'm going to Disney World in July and I certainly would like there to be
less of me there lol. I figure I have 2 whole months to work at it, but it's gonna be a struggle..just have to keep the will power up and no cheating..
So what's everyones game plan as to how they are going to lose weight? Any special diets...what kinds of exercise? For me, I'll probably follow the Fat Smash Diet for a while and then switch off to the basic watching what I'm eating and exercise (tapes, walks or the gym) everyday.
Good Luck everyone~
