The trip to Port Canaveral:
Awful! We were up 19 hours which is too much for someone not in great health. The bus ride was not bad. Luggage handles well.
The ship:
Better than expectations. Plenty of room even with wheelchair. Lots of storage. Bathroom much better than expected. View would have been better 3 or 4 rooms down (ask for Street View not Promenade) unless you want quiet. Our room was almost sound proof! Bed was great!
