the trip started out badly when we got a notification that our credit card was hit for $200 by Carnival before we even left on the trip. What! Called and told this was 'normal'. Requested a handicap cabin for spouse, It was a standard cabin with a normal shower stall but had a pull down seat. Had to take handles off scooter to get thru door. A foot high step to get into bathroom and a step (normally a ramp) to access balcony. Had to get a chair removed so we could even move in cabin with scooter in cabin.
You'll love this one. the cabin safe require a credit card or drivers license to open/close. No, they didn't charge for use, but if we used my license and wife wanted in safe and I'm out on the ship somewhere, she would have to hunt me down to open safe. Instead of using the cabin key (used for everything else, rigtht?). Oh, and lockers in the gym were keypad, 4 digit open/close. DUH@
New rule: ship can't leave until all CPAP users verify they have them in their possession. They called the cabin 7 times asking if we had the CPAP. Each time the answer was the same, haven't received luggage yet we'll call you when it arrives. Oh,, and be prepared to pay for the needed distilled water.
comments above cover all aspects of cabin.
