We chose Royal Caribbean this time because we wanted to try something different and had cruised a few times on Carnival and enjoyed it. Overall the cruise went well the destinations and excursions were very good and crew was courteous and friendly but not as friendly and personable as Carnival simply for the fact that there was 7,000 people on board this monster of the seas. We reserved a dinner at the Chops Restaurant and between the appetizer and dinner we waited two long hours. The Staff finally had other staff members from other restaurants come to help. The lines were long at the bars in the pool areas during certain peak times in the day and the promenade was always packed with people as there was always sales on watches and purses as you would have thought you were at a mad flea market. The only time It was not crowded was after midnight. There were a lot of parties of passengers that were celebrating some sort of event birthdays or anniversaries and some got very loud and out of hand in certain areas. The Cabins I give a 5 star rating as everything was very clean and comfortable. If you like a very crowded cruise on the largest ship I have ever been on then Oasis of the Seas is for you.
