Cruises are great. I took a cruise over the holidays, and it was pretty easy to stay LC. You can order anything you want for breakfast, do buffets for lunch and while there is a menu for dinner you can tell your waiter about your special needs and they are happy to help. I never went to the midnight buffet, and avoided all the dessert tables. I had a great time. My brother was with us and was on Atkins, and loved all the bacon, sausage, smoked salmon, steaks, fish, lobster and salads. He lost weight on the cruise, too.
Have fun!
