My guess is that if you just started and got the starter pkg you don't have any ready to drinks? Those are the easiest way to go when traveling. You can add them to your next order!
As for this time around, I did the same thing on a trip my second week into the program. Couple of tips:
Hot chocolate, chai, and capuccino are great for "hotel breakfasts" where they have HOT water available. No one really notices the difference!
Shakes travel very easily. I used little 8 oz bottles of water, opened and drank a sip, snipped the corner off of the packet (so the opening wasn't so big) and poured into the bottle. I shook it up and drank it, and then was able to pitch the bottle rather than carrying it around! It worked out very nicely! I also have a couple of rubbermaid "juice boxes" and one shaker/drink bottle by rubbermaid that would work just as well if you are in the hotel room.
Also, some hotels have hot water in the lobby, and some of the more basic soups (chicken noodle, tomato) are easy to prepare.
You might want to stay away from ones that have to sit awhile, like chili and minestrone.
Also, bars are very portable for times when you are out and about!
I have found restaurants to be extremely accomodating as far as the LNG is concerned. Most will replace starches with extra veggies or a salad, and that eliminates a lot of temptation.
Most of alll, have fun and enjoy!
Good luck!
