I have decided to write this review because after over 15 cruises on over 10 vessels, this particular boat has been my favorite!
A little perspective- I have sailed with Disney, Carnival, NCL and Royal Caribbean. I traveled with my husband and our 3 kids all 8, 6 and 2. We are not port people and usually take those days to enjoy the ship's pools and common spaces. Disney is our favorite cruise line, and still is, but Oasis is, as mentioned, is now our favorite boat for the shows and things to do and overall layout.
We had 2 adjoining staterooms and were comfortable although the staterooms felt a little smaller than Freedom of the Seas or even Carnival adjoining rooms, but it was fine. We are Gold with RCL so we had a shorter line for check in but I have to say it was pretty bad; we were at the desk for almost 30 minutes as they needed a supervisor/trainer help with every step and our agent wasn't the only one who needed help. Seemed like some simple logistics, like giving every agent a hole puncher to punch cards for lanyards would make a huge difference. My take away here is GET TO THE PORT EARLY IF POSSIBLE. We were at the port at 10 am and it still took over 2 hours to get from the front door to the boat.
