I've been on a cruise and loved it. A quilting cruise is a dream trip for me. Hopefully someday!
A friend from our guild when on an Alaskan quilting cruise organized by www.sewmanyplaces.com last year. She had a great time. At least I got to "see" it through the presentation she did for us at a guild meeting. She had lots of quilting time, machines provided (sorry, don't know the brand), but still had lots of time for seeing scenery and shopping at LQS while in port.
