WE just got back from a month long trip in our RV, and it was very hard to stay on program without access to a blender and microwave! (The one in our RV just stopped working one day, go figure) I ate a LOT of bars and got really sick of so much sweet & crunchy! Yech!
But I discovered that 3/4 cup of Safeway's "Best of Egg" (Eggbeaters) is equivalent to a MF scrambled egg, and could cook that on the stove. And there are stove top instructions for most things on the MF website. http://tsfl.com/pdfs/resources/Mixing_Instructions.pdf
Of course you have to have access to a stove or hot plate! Hotel rooms often have microwaves now, so that might not be a problem for you.
But we ended up eating small Lean and Greens throughout the day, kind of like being on maintenance. I actually lost weight still, although my rate of loss slowed drastically. At least I didn't gain anything back, TG!
