Yes, I have been on two cruises to no-where. Both ships had a formal night and yes I would do it again.
My last cruise to no-where was the inaugural sailing on the Miracle in Tampa. It was so exciting, and the new media was everywhere taking pictures. There was a helicopter that was flying over head taking pictures. It was just enough to experience the ship and see if I would like to take a seven day cruise on the Miracle. If you are wondering, I would not hesitate.
