I don't think I gained too much on the last 7 day cruise with all the walking I did. The dessert temptations always seem to be the culprit, or having the cheeseburgers on the Lido deck.
I normally don't gain much because I walk everywhere. However, the sweet rolls in the mornings and desserts at night, well I wear my tighter fitting clothes at the beginning of the cruise, just in case
Right on Penny, I always wear the tighter fitting ones early on, although I only put on 4 lbs this last trip..I think it is the walking and the tropical heat that does it to me.
