Carnival all the way.
We book inside cabins and the one NCL cruise was on the Pearl and it had a terribly small inside, could hardly move around the bed to get in or out. Service was just okay, realised that the cabin stewards have too many cabind to take care of and the main dining room food was just barely okay and the service was horrible. NCL does not want you to eat in the main dining rooms they want you to eat in tehextra charge resturants. We did not try any extra charge but did try a couple of alternitive resturants and getting a reservation was a nightmare. NCL says Freestyle, well except for the main dining room and buffet you have to have a reservation and I do not call that freestyle. Carnival's your time dining works much better.
The only way we will cruise with NCL again is if our grandson does another contract and we cruise on his ship.
