Did a Carnaval cruise in Feb, with a local QS It was Ok, sewing was a little tricky, because of the motion of the ship, but nothing serious. We brought our own machines, I had no trouble with that, (I have a Kenmore Mini I use for classes etc.) It was great meeting some of the other quilters. As for your group. Make sure you check on what is supplied. Irons, in particular can be a problem.
