I have cruised on all of those cruise lines and been to all the cruises on this side of the Atlantic. Of all of them I was the least pleased with Carnival. That was before their recent troubles. I am not sure I would want to drag all of my sewing and quilting stuff with me on a ship. While you soon get used to the motion I am not sure how that would work when you were trying to use your machine etc. I am sure I took some handquilting with me as I always have something to work on by hand. Most of the names of the teachers I was not familiar with and I actually belonged to a group of professional quilting teachers and speakers that are active in the Mid Atlantic area. I hope someone else who has been on one of these cruises answers your inquiry. The other question I would have is what are you going to do with your hubby? I physically would have a problem without mine as I am leagally disabled.
