Another vote for POR mansions, hands down.
I did a solo, all resorts, no parks trip for 8 days two years ago.
I was in a riverview corner room in Parterre Place, not 30 feet from the river.
I was near the foot bridge that went over to the front of the main building, so it was very easy to get on the water taxi at 10:00 am for a late breakfast. I walked around DTD, or took the water taxi over to SSR, sat on the deck and had munchies at the Turf Club. Spent one day at the spa.
Used the DTD hub to get over to the resorts for dinner each night. One night I did take the bus to DHS, then took the friendship boat over to BWI to go to Kouzzina's.
There are so many different modes of transportation, it is so spread out, so it is so quiet. There are so many different experiences you can have staying there.
Highly recommend.
