It's been a number of years since I sailed on Carnival, and I was pretty skeptical of the Glory based on some of the negative reviews (and the alleged noro virus). I traveled with my sister and 2 nieces, age 13 and 19. I ended up having a good time and a new appreciation for Carnival.
Embarkation: We got to the ship quite early (10:00). Our luggage was quickly checked in, and we were led to a waiting area for a brief period. Soon, they let us begin the check in process, and after another brief wait, we were having board by 11:30. I heard the lines get pretty bad by 12:00, so early is the way to go. We were able to go into our cabin by 12:30, although not all cabins were available yet.
Ship: The Glory is a large ship that was sometimes difficult to navigate. They should do better with the maps and signs. Decor was mostly tasteful, and the ship was generally clean. Lots of bars and lounges, and the Amber Palace was really pretty. The casino is large and noisy, but that's not a bad thing for me. There was a strong smell of smoke, particularly on the last night, as if their fans weren't quite working. The pools on board are small and crowded, but I wasn't brave enough to go into the cold water anyway.
Small shower with no shelves to hold toiletries. Across from laundry room, which can get noisy.
