I love small ships and had sworn I would never sail on the Oasis of the Seas. But, when "Make-A-Wish" offered us to sail with them on the inauguration overnight cruise, we relented. Wow, what a ship! The Oasis is like no other ship ever created.
My overall impression is that RCCL does not want you to know you are on a ship. The seven "neighborhoods" create towns, parks, shopping malls, water parks and outdoor fun centers without you ever knowing that you are on a cruise ship. It is generally modeled after Las Vegas and Disneyworld, and you have to make an effort if you want to see the ocean.
The cabins are outstanding. The spa is reminiscent of Canyon Ranch or any other large, luxurious spa. The gym is as large as LA Fitness and packed with tons of brand new weight machines, treadmills, ellipticals and other assorted goodies. They did not scrimp on cost anywhere on the ship.
Walk-in closet was huge. Plenty of space in the cabin for 3 of us. Large comfortable balcony. Bathroom size was large. Lots of electric outlets. Lighting was good. Bed was great. Light switches at entrance to cabin were confusing.
