Hi Michail Mel and I recently cruised for a week. Our problem however seems to be that he is affected by the motion of the boat and gets confused. We resorted to the wheelchair which helped and we had a great time. Some night time hallucinations as expected. We took a 40 yr old who pushed the chair as I did have open heart surgery 2 yrs ago. We had a great time-watch the casinos, ha. Took us for a bundle. The people at our table were great and the staff wonderful, cutting up the meat and really giving me a vacation. Mel fell out of the bed several times but son was up and helping. Like us we make the most of mobility and glad we went. Next time will take a larger boat and not so rocky. Worst thing was Amtrack train with a room but motion impossible. Went to Seattle and flew bad. We were 'sleepless in Seattle, motion of train a bummer. Mary, CG for Mel 75/11 IYQ
