We went on a cruise a few weeks ago. Had a wonderful time. For anyone who is interested, anyone who might go on a cruise and reads this thread. Your main dining room (evening) server should be able to request sugar free desserts for you. Our server made sure they had sugar free desserts on the buffet in the casual dining room since he knew we would be eating there. He even had desserts sent to my room every evening. I came back from our 7 day cruise 2 lbs lighter than when I left. I had no trouble sticking to my WOE, I even had a few drinks...frozen margaritas..yum yum... The cruise line was Royal Carribean, Ship was Explorer of the Seas. Just so you know who is willing to bend over backwads to make you happy.
Worth every penny we spent on the cruise. Would use Royal Carribean again in a heart beat!
