I was on Quantum in January 2015 we stopped in Nassau right next to the Dream, how I wished I could sneak onto the Dream. That cruise, for us, was the worst ever. Granted she was a new ship, but the list of what went wrong......you can google her holiday cruis of 2014-2015 to see. Unfortunately we were on the NYE cruise. I digress, the ship had a poor layout IMHO. It was a lot of wasted space, like a whole lot. Quantum was definitely noticeably bigger than the Dream, but the Dream is much, much nicer.
