We just returned from a great cruise on the Disney Dream. We had only one day of bad weather due to Isaac- rained all day on Sunday. The Captain did a great job docking at Castaway Cay on Saturday in the wind- he was determined to get us there. Serenity Bay, the adults only beach was wonderful.
Disney did a great job pairing us for dinner with 3 other couples traveling without children, and our server was excellent. We did eat at Palo, one of the adults only restaurants one night- very nice!
The adults only pool was a welcome area as well, and it is great that the hot tubs look out at the ocean. The adult pool was really only busy one afternoon. No idea how the kids pool or family pool were as we avoided them except when walking through the area.
We spent some time at Meridian (bar between Palo and Remy) which had great views, Skyline Lounge (where the windows change to different famous cities), and 687 (the sports bar- with recliners!). All of them were adults only as well.
We enjoyed the 3 main shows (Villians Tonight, Golden Mickeys (which we had seen before but has been changed some since then), and Believe. Believe was the best but enjoyed them all.
I enjoyed the midship detective agency and finding the missing puppies. The interactive artwork is great.
Unfortunately, did not try the Aquaduck- next time!
Overall, a great cruise. If you are an adult traveling without children, it helps to love Disney, but you can easily find spaces dedicated to adults on the ship.
