We took this cruise with our two daughters (1 and 7). The service was impeccable, and it was perfect for our family of four.
Service: Cruising in a suite introduces a whole new level of attention. I don't think I can ever go back to a "normal" stateroom. Our gold sea pass cards where our keys to whatever we wanted - last minute character dining - no problem - special help disembarking - no problem. On top of it, our Suite Attendant Rosen was unbelievably accommodating and super friendly.
Babies: Unlike many cruise lines, this fleet has a special dedicated splash pool for babies in swim diapers! (On most boats, those diaper clad kids can't go in any water.) The nursery staff was great with our daughter and scheduling was not a problem.
Awesome room with plenty of space. Beautiful views from the double balcony. Dual lounge chairs plus a little breakfast table on the balcony. Suite attendant for this room was great too. Mid ship, felt some movement, but not too bad. Use the forward elevators for less of a crowd.
