I just got off the Dream from an Eastern Carribean vacation with my wife and three children (7,9 and 11). We were first time cruisers. We all stayed together in a family ocean view cabin on Deck one. Here are my observations.
Embarkation: Very easy and very quick. Even at the peak time we were out of the car and on the boat in less than 20 minutes.
Cabin: Although I have nothing to compare it to I thought the cabin was great. We had a king bed for the wife and I, 2 Pullman beds from the ceiling for the oldest 2 kids and the sofa bed for the youngest. This room would be tight if you wanted to spend a bunch of time doing things together in the room like eat. But for sleeping, changing and all normal vacation activities it was just fine. Beds were comfortable. The two baths worked out great for us and the 4 closets held all of our stuff and then some.
Nice cabin. midship so it is quiet. ocean view on the first level. It was great for the 5 of us.
