My husband and I just returned from the Oasis of the Seas Western Caribbean. We really had a wonderful time and the staff were very nice and helpful. The Oasis is a beautiful ship and has many things to do all the time. You can never get bored! I am sure that we did not get to see the entire ship. We did the My Time Dining and never had to wait more than just a couple of minutes. We will get to our two concerns in a moment.
First, our Stateroom attendant "Carl" was fantastic (We were on the 11th deck). He went out of his way to help us and we needed additional assistance because of medical problems. He always had a smile on his face and took care of any requests that we had. Since we did "My Time Dining", we paid our tips ahead of time but we gave Carl additional because he was so great!
Second, our Dining Room Waiter "Hemant" (we were in the 5th deck dining room). He was very personable and took a lot of time with us. He let us try different entrees and desserts and really made sure we were satisfied with our meals. His smile and interest in us made us feel "at home" all the time. We also gave him an additional tip. The food was exceptionally good and do not miss the "Izumi" restaurant. It is the best on the ship.
Since the cabins were one of our concerns, we were not really happy with them. Everything was exceptionally clean and our stateroom attendant was the best though. The rooms were quiet, we had a great view, the closet was not really too small. The bathroom was small and we did have that concern. There were no outlets in the bathroom nor enough in the room for that matter. There was just not enough room to walk around someone else in the room. Although the balcony was small, it was OK. The dividers were not private and you could see through and around them easy!
