The Oasis of the Seas was magnificient. The only draw back was the facilities were too small to accomodate this many people. Windjammer Marketplace buffet was too small considering the humongous size of this ship. They have a constant annoying PA system recording telling people to leave after eating so others can come in. A very stressful eating experience.
You need advanced reservations to see any of the shows for the venue is too small to fit a large group of people. Could not get any reservations to the comedy club all week for the place is to small (as if the ship holds only 500 passengers). Even needs reservations to anytime dining for the line was too long if you don't have a reservation.
Also, one of their specialty dining the Giovanni's Italian restaurant.... the chef or cook needs to revamp their menu for where in the world will you eat in an Italian restaurant and order meat balls with no pasta on it? Only in the Giovanni's Italian restaurant of the Oasis of the Seas.
