If I had to choose? I'd move the CR or Poly to the Epcot area, but keep momorail access. That's a choice right? Actually, I love the CR, Poly & GF (in that order) resorts the best, but the location of the YC/BC or BWI can't be beat. So if I had to pick a permanent home, it would be the YC (DW's favorite since I surpirsed her with a trip there a few years ago).
We love the WL, we keep going back. We always say..."let's stay at the BC or AKL"...but we just love the WL. A lot depends on what park you will be going to the most. MK...definatly Poly/GF/Con/WL, Epcot then the Epcot hotels.
I really love the Poly! We stayed there last summer and it was fantastic! We tried the Beach Club in January, and I wasn't overwhelmed, I Just kept thinking of the Poly and the ease of the monorail, with our 2 1/2 yr old!
I love the MK resorts! Once we tried them we haven't been able to leave them. I want to try the Beach Club but I love being on the monorail and next to the MK.
I love the WL but have never had the opportunity ($) to stay at one of the monorail resorts. I had to vote for those because I am dreaming of the day I get that chance.
