Here is my review of the Ruby Princess...
We were a group of six ladies - myself, my mother, daughter, sister in law and two nieces. All over the age of 21.
Embarkation: GREAT! The process was easy - we arrived at noon and the we were on the ship in less than a half hour. We each had a bottle of wine that we checked in. They didn't even open the bags - just felt it for the proper size. We went straight to our rooms which were ready! On previous trips with Norwegian , rooms were not ready for a couple hours after boarding. We each had inside cabins, which were a nice size - larger than I expected, as I have only had balcony cabins in the past. We were missing the shampoo/shower gel bottles - did not receive them until day 4 (yes, we asked for them) - glad we brought our own.
Our stateroom was a nice size and very comfortable. This was my first time with an interior room, and while I did miss the balcony, it was very comfortable.
