This was our 12th cruise and 2nd on Disney. The others we have sailed with - Celebrity, Princess, RCCL - all offer a good product (i.e. cruise experience) but IMO Disney does it all a notch better (sometimes several notches better!)
The Dream is beautiful! From the chandeliers, to the brass and woodwork, use of color and themes it is visually impressive. The amount of technology on board is staggering. I could not possibly describe it all and therefore refer you to their web site. We noticed some nice additions to the Dream compared to the Wonder. These would include the use of on board cell phones, additional adult-only areas, and of course, the Aqua Duck!
We found the service on board excellent. Our cabin steward, wait staff, and everyone we met in between was friendly and helpful. The entertainment is beyond compare. Finally! "Broadway-like" shows that actually are!
