Well, I'm back from our cruise.... We had a GREAT time, now I can't wait to book another one! This 3 days went by very fast, but was good as a 'refresher' cruise.
Many of my fears were unwarranted, the people in Nassau were great and even though the ship did get rocky, it wasn't too bad. The dramamine put us to sleep rather than avoid motion sickness. We lost an entire night to sleep.
Thank you all for the advice, prior to my trip.
