After having lost over 30lbs this past year Im greatly concerned about gaining over the cruise. How much did you gain? If not much, how did you manage to keep it off? Walking deck, dancing, etc? Did you tell waiters you were on a certain diet? Ever slack off? on what? Pls dont say "Its a vaca, worry about it when you get back" Ive worked too darn hard to gain it back. Afraid my new clothes wont fit when I return if I go with that mindset.
