I stay at POR, and last year I did an 8 day, all resorts, no parks solo trip and it was great.
I was able to take advantage of taking the DTD bus back from the resort, and then the water taxi back to POR.
Also, there are a lot of nice restaurants at DTD; Paradiso 37 is my new favorite, but I also love sitting at the bar in Rainforest Cafe and watch a football game in the afternoon.
If I could afford to go deluxe, I would do WL. They have a wonderful lobby area for people watching, great pool area, and the bar is very nice and has a lot of nice snacks. I go out of my way to get there every year. I have met a lot of people there, a lot of my own age.
