We had been on this ship last year and had no problems. This time our stateroom was aft. Right above the engine room. For 45 minutes after leaving port and before docking the noise and clatter was horrific. Items slid off the shelves, the room shuttered, and it all sounded like there were loose items in the engine room bouncing around and hitting the walls. To all who sail on the Grand Celebration out of Palm Bay, Florida - do NOT accept an aft room. You will be charged the same amount as a forward room and you will think you are in a chamber of horrors. The room was clean and the housekeeping person was very nice. Many of the slot machines were out of order. The excursion was trip around the island and ended up at a beach where we had lunch. That was enjoyable. We did get 5 drink coupons - that was good.
