We were on the Dream in early June. We were in 8188, which is the aft-most room on the deck. I've been on about 20 cruises (this was only the second on
DCL), and part of what I love about it is the gentle vibration. The vast majority of the time on the Dream all we had was the gentle vibration that puts me right to sleep. HOWEVER, whenever we docked, there was significant shaking. Not vibration, rough shaking, as in it knocked some clothes off the hangers and made everything out on the flat surfaces rattle loudly or fall off the flat surfaces. It usually lasted about 30-45 minutes. When it was at 6am, we just sighed and started our day early. But when it happened at 4am, it was frustrating. Luckily, the 5yo didn't wake all the way up. We were on a double-dip of
Castaway Cay, so one night we knew we were going to be woken up early with the rattling, and we did. My DH wondered what that rattling would have been on the Richter scale. I will say that we were cruising with some weather, so perhaps the weather exacerbated the problem. Also, perhaps being the aft-most room didn't help. We loved that stateroom, so I don't know if we would avoid it in the future, but it's something to know about.
