Just got back from a week on the MARINER in a Family Suite - it was the absolute best way to go for our family. Kids had interior bedroom (2 beds, 2 pullman) a walk-in closet and their own bathroom with shower. Parents had master bedroom with 3 closets, tv, and master bath with Roman tub and marble counters. The living area had a dining room table with 4 chairs, 2 club chairs with stools, a sleeper sofa, refrig, tv with surround sound, dvd and stereo. Balcony was 200sq. ft - HUGE! It had a round table with 3 chairs and 2 chaise lounges. If we didn't want to deal with the crowd at the pool we could lay out on our own balcony. Our cabin was 8694, at the very back of the ship, and our balcony was literally 1/3 of the width of the end of the ship. Conceirge service was cool- there is a private key to the conciege club in your room along with Royal Caribbean stationery with your name imprinted on it. The Concierge was wonderful and she would bend over backwards to do anything for you. Concierge club had free happy hour with appetizers, continental breakfast, and about 200 DVDs and CDs to borrow.
For our family, this was, by far ,the best way to go on a cruise - well worth the money!
