a while back, i exchanged personal messages with somebody on the mm.org board. can’t remember who right now but remember he was really nice. anyway, i had commented in some random thread that i would never be able to go on a cruise. he took the time to pm me and tell me his story. if i am remembering correctly, it was something to this effect. he and his wife had always traveled. since having mm, he had to quit. she begged him to try a cruise. he did and he was just fine on it! he said they have gone on to do several more cruises and he was always fine. he said the larger boats have good stabilizers that really negate that rolling feeling. he also had some good advice about the best place to get a room on the ship to avoid rolling. unfortunately, i don’t remember that right now. seems like it was in the middle and not too high up. i still haven’t tried a cruise myself but that gave me some hope. if you want, i can dig through and see if i remember who he was and let you know.
hope you have a blast!!
