Much information has been provided already on Oasis of the Seas, but this review will provide details of our experience.
Precruise: We stayed on the Hyatt Place North. This hotel was in a good location, with many dining options within walking distance. We walked to Bimini Boatyard and enjoyed a wonderful dinner. I can recommend both the hotel and the restaurant to anyone looking for a nice place to stay and eat. We used a taxi to get from the hotel to the terminal, only because I don't like to arrive to the terminal in a mass group of people. The Hyatt North offers a shuttle to the pier at no cost.
Embarkment: I read about it on Cruise Critic, but still couldn't believe how easy check in and boarding was. We were on the ship within 20 minutes of our arrival at the terminal. We arrived fairly early, and had a wait of about 10 minutes in the Platinum waiting area of the terminal.
Larger balcony, good location, quiet.
