I took this cruise with my my wife and 2 children under 3, along with my inlaws, who had their own child under 2. The 7 of us were booked in a single Royal Family Suite, which proved to be too small for this many people. We made the best of it however, and one child had to be sleep in the walk in closet in a Pack N' Play with the door always partially open. One of the two bedrooms simply has no open space other than the bed.
I slept in the Master Bedroom, which had a bathtub shower combination and a little open space. We were able to just barely fit a Pack N. Play and fold out cot for our two children. Space constrictions aside, the room was well furnished, with flat screen TVs in each bedroom, and a 40" flat screen and DVD player in the main living area. Our room attendant did an amazing job cleaning up after our little ones, and left us chocolates and towel animals each night on our bed.
The benefits of booking a suite including priority seating in the theater, and access to the concierge lounge. The concierge lounge turned out to be the best part of the cruise, as many in my family agreed. Reyno, the concierge, was very helpful, and assisted with booking a last minute excursion. The open bar and canapes each evening before dinner were wonderful, and this became a daily tradition for our entire extended family. If you ever book a suite on a ship, you should really take advantage of this VIP feature.
