We got off the Fantasy last week and had a great cruise. We had an Aft stateroom and although I have no problem with general ship movement and sleep great on cruises typically, we felt a lot of vibration when in the room. Was this a function of the location of our room or the new ship? We are booked on the Wonder to Alaska next summer and currently have another aft stateroom. Wondering if we should move rooms. Thanks all!
