We are two parents, one brother-in-law, all in our early 50's, and two teenagers. This was the third cruise for the family, first time for BIL.
Embarkation: Easy. We got to the port around 11:15 and were sitting at lunch by noon. Wear your bathing suit, or pack it in a small bag so that you can go right to the pool. Our rooms were ready by 2pm, but all of the bags did not arrive until 5pm. We didn't care, since we were already poolside.
Cabins: We had three inside cabins. Smaller than other ships, but really fine for a short cruise. I always bring a hanging shoe bag for shoes, socks, goggles and other small items.
Small inside room, but certainly adequate for 2 people.
