If the past four days at the volleyball tournament are any indication I would probably not stick totally to lo-carb. There would be lots of meat, veggies, etc on the cruise so I wouldn't go nuts but if there was something that looked interesting I would probably try it.

I'm paying big bucks for my cruise and if there is food there that I've never tried before and likely will never try again, I'll probably go for a small spoonful of it just to see what it's like.

I think if I eat reasonable amounts of food (stay within my daily calorie allotment) and get lots of exercise touring the ports I should be fine weight-wise and if not there is always induction when I get back . Oh by the way I also am going on a cruise in August to Alaska to celebrate my 25th wedding anniversary.
