Just checked out of the Dolphin on Monday. Loved it, loved it, loved it. Spent 5 nights there after 4 nights at Pop. The difference is incredibly striking. That was our second attempt at a Value, and only because so many people here rave about Pop. And while I don't have any complaints about Pop, and while I don't want to denigrate what is obviously a favorite of a lot of people on these boards, I'll just say we won't ever stay there again. I think we're just not Value resort people. And I am trying to say that without making any value judgments (no pun intended... well, mostly not).
Anyway, back to the Swan/Dolphin. What's not to love about it? I find the threads where people worry whether it will feel "Disney" enough. Like because there aren't Mickey heads in the wallpaper and on the soap, they just won't feel like they're at Disney. Well, fine. I look around my room, and I don't see anything Disney (except all the stuff I bought!!). But I walk out onto my balcony and I can see Epcot; I can see the sphere, I can see the Eiffel Tower, I can see the parapets on the castles of Germany, I can see the Boardwalk and the Friendship boats traversing waterways. I can see lighthouse at the YC/BC. I can see people in their Surreys struggling the peddle up the hills of the bridges, and see passersby pitching in to help by pushing them that last few feet

. At night I can see all the twinkling lights of the Boardwalk, I can see the Epcot fireworks, and if I really look closely, I can see the people on the beach at the YC/BC watch Cars on the movie screen they have set up.
Last Saturday night, my DD5 was kind of tired from an intense week, and didn't want to go to Fantasmic. So she and my DW walked to the Boardwalk for an ice cream sundae and took in some "street" performers, while my DD7 and I took a boat to MGM, watched Fantasmic, then walked back to the Dolphin.
Where else in the World can you get all that? None of the other Disney properties can match the setting of the Epcot resorts. Only the GF and Contemporary with their views of the MK could come close. But even those (very expensive) hotels are a long bus ride to all the other parks.
Those are just some of the things I think you'll find are "cool" about the S/D.
