This review is for the Oasis of the Seas from May 2016. There were three travelers - mom (me), dad and son (3 1/2 years old).
The ship is huge and amazing! Based on the number of people on the ship, I expected everything to be crowded and to have long lines everywhere... much to my surprise and delight, there were hardly ever any wait times for the things we wanted to do and the only "crowded" places were the promenade and pools on days "at sea"... but even with the crowds you could still navigate around and find seats at one of the pool areas (maybe not your 1st choice seat, but you could find something that worked).
The ship is BIG be prepared to do a lot of walking!
We enjoyed the Boardwalk Balcony. 90% of the time its not noisy... when the aqua show is going on you will hear it and one night they had a dance party until 11pm on the boardwalk... other than that its just fine. You get to see the aqua theater from your balcony and you can see the ocean too!
just walked around the port
Columbus Cove beach was the best spot!
