I don't remeber the cabin number but my friend and I booked a guarantee inside cabin on the Sensation. We were thrilled to get a 4 category upgrade. We wound up across the hall in an outside cabin. Since we were almost all the way forward, the cabin was a rather unusual size due to the curve of the ship. That wasn't too bad though. What we didn't realize was that we were right over the anchor chain. We found out about the chain when we docked at 6:30 AM. Who needed an alarm!!!! So beware of forward cabins.
