In the Pool and Sports Zone, Oasis of the Seas' top-ship neighborhood, you'll find a "zero entry" pool that's great for gradually wading into deeper water; a sports pool (think water-jousting and pool volleyball); and the H2O Zone that's just for kids and features several brightly colored water-spraying sculptures.
Oasis of the Seas is the first cruise ship ever to feature its own zip-line, which runs diagonally across the Pool and Sports Deck, above the Boardwalk. For those who dare to try it, the zip-line offers an amazing (and free) aerial view of the carousel and other attractions, so be sure to look down! You'll need to sign a waiver, obtain a wristband and prepare for what could be a long wait. (It will take about 10 minutes just for the staff to harness you properly.) You will also be required to empty your pockets and wear sneakers and a helmet. This is definitely a fun option, especially at night when the Boardwalk's festive lights are aglow. However, it may not offer much of a thrill for passengers who have already tried land-based zip-lining, which usually offers a longer and more picturesque experience.
There are also two FlowRiders, the surf simulators that made their debut with the Freedom class. Both are located on Deck 16 aft, with the Wipeout Bar wedged conveniently between them. One note: If you're intrigued by the FlowRider and have never surfed before, we suggest boogie boarding first. Surfing isn't as easy as it looks, as one of our staffers found out the hard way (see our Oasis of the Seas FlowRider video
Despite a vast spa facility, the ship's gym, which has been moved from Royal Caribbean's more traditional top-deck, full-windows locale to amidships and is illuminated by stingy portholes, is underwhelming. Parts of the spa itself also suffer, ambience-wise, due to the new location (particularly fluorescent in feeling is its salon, which has no outside view to the sea at all). One nice touch: a stairwell inside the gym leads directly down a deck to the ship's running track.
Our spa experience was particularly ... stressful, which frankly defeats the purpose of going to a spa. Staffers were disorganized (didn't reserve the treatment properly, charged more money than I was quoted, mixed me up with another passenger, then gave me a hard product sell afterward). Ultimately the spa manager did refund the disputed amount but she was snarky and unpleasant. I was so disgusted I decided to skip other treatments I'd planned to book.
Other down-notes on the ship's spa and gym facility include the fact that the gym is a deck above some treatment rooms and noise there can intrude on the supposedly serenity-inspired ambience below. As well, the ship's anchor appears to be located just underneath the relaxation room and the noise is quite audible at times.
Prior to taking the cruise I was quite enamored of the adults-only, glass-roofed Solarium, but after being onboard I was ultimately disappointed. It was always packed -- very difficult to find a chaise -- and the spare furnishings were simply sterile rather than hip. It wasn't as warm and welcoming as it could have been (Princess Cruises
definitely does a better job with the concept with its Sanctuary spaces) and perhaps there's some way to moderate the crowds.
