This was our 5th cruise, 1 AMA (Danube), 2 Norwegian (Alaska & Mediterranean), 1 Princess (Baltic). We were not expecting much from Carnival and WOW! We were surprised!
We had a spa room-deck 11 (1107) which entitled us to unlimited access to the spa the entire time. The room was great, bathroom just fine, storage more than enough. Spa was incredible-better than any on land I can remember.
Service from everyone - waitstaff, room steward, bars, service people, spa, excursion, embarkation, etc., were all well trained, well informed and friendly and polite.
Room was great.. Plenty of space for everything. Enough closet, shelf and drawer space for the 14+ outfits and coordinating jewelry and shoes I brought (plus my husbands stuff). Plenty of room in the bathroom-spacious by cruise standards. Decor nothing special. Best part was the free access to the spa which was right around the corner. We did not feel "rock" except for one night where it was bad no matter where you were on the ship (most people didn't even come to dinner that night) but the motion of ships don't bother us too much anyway)
