The Oasis of the Seas is by all accounts is an architectural and design wonder. In a private tour of the Oasis of the Seas, Royal Loft Suite you will the inside one of my favorite new innovations on the Oasis of the Seas. The new Loft Suites on the Oasis of the Seas takes the Cruise Ship stateroom to the next level. On the 17th deck, Royal Caribbean has varying sizes of their new loft suites.
