We were on the same cruise (8/28) as MoranClan. The Captain did a fantastic job keeping us away from any rough seas. In fact, we never had a day of rain! The only "rough seas" we hit were coming back through the Gulf on Sunday 9/5 at the tale end of Frances. A lot of people were taking Bonine and Dramamine, but we never saw anyone actually getting sick, and the dining rooms were full! So enjoy yourself and don't worry about it.
