My husband and I embarked the OOTS in Ft. Lauderdale the same day we disembarked the Celebrity Reflection in Miami. In retrospect, we should have just stayed on the Reflection but at the time we booked, we thought it would be fun to explore a new ship that was getting so much hype. This was our 7th cruise having sailed with Celebrity and HA (for reference-we are 31 and 33 years of age). I felt like the daytime activities at best were reminiscent of a college spring break trip (belly-flop contest anyone?).
I should say that we do not have any children and this ship is geared toward such. So much of the ship is dedicated to families: main pool area, front of the ship with mini-golf, boardwalk promenade. That being said, RCL does do a good job at "hiding" the kids club activities. Personally, the flash mobs, Shrek Gangnam Style Dances and Dreamworks parades and character meet and greets were just too much for us.
EMBARKATION: Quick and easy-nothing remarkable. The muster drill was lengthy and unorganized (we were set up in Blaze nightclub)
