My family and I are going on a cruise over Thanksgiving. We've cruised before, and I know it can be a real eat-a-thon. For some reason, I feel very confident that I'll be able to stay pretty close to program (I already know I'll drink too much, and I'm going to have full Thanksgiving dinner--a planned cheat). I plan to walk around deck every day to get some exercise to help counteract the extra alcohol, and I'm going to pack some bottled water since it can be very expensive on board.

Has anyone else here been low-carbing on a cruise? Any other tips you might want to share with me?
