I just got back from sailing on Carnival Glory to the Western Caribbean on 2/26. I am a 16 year old girl so remember that this is from a kid's perspective. I have been on two other Royal Caribbean cruises but this is my first on Carnival. We were the last bus to arrive at the ship, so all our paperwork was done on the bus and there were no lines at all to wait in which was great. Less than an hour later we were moving.
We had an inside room it was nothing great but for the amount of time that you're in there it is fine.
We had dinner in the Platinum dining room and our waiters were excellent. They were always doing whatever they could to help you. We sat with another family and we had a great time with them. I went to the teen club Ultraviolet on that night and met other people my age. If you have kids you should tell them to go out to the activities they have for them because you meet a lot of great people and will have a lot of fun.
