Looking for your favorite resort near Epcot. There will be 5 adults so a great pool is not a high priority. Also one who is not able to walk far so recommendations on best rooms to ask for. Thanks
we've stayed at BWV (own DVC there) & BWI, YC, BCV (own there also) & BC.
for an adult - or family with older children - trip, top pick would be either BWI or BWV, followed by the YC. nightly activities on the BW include street entertainers (magicians, rolling piano, etc), carny games, surrey bike rentals, as well as a microbrewery, ESPN, dueling piano bar, dance hall. Flying Fish restaurant is excellent, and a new Italian restaurant has recently opened there. Belle Vue lounge (inside the resort), is a great place to have a drink with friends.....or just to make new friends

Despite the nightly activity, the interiors are quiet (and beautifully elegant). I know you said you didn't care about a pool. but BWI has our favorite pool on property - a gorgeous oasis in the middle of WDW

.
YC is also a fantastic resort for adults and older children. It is small, quiet, with an upscale nautical theme. YC, along with BC/BCV, about a 10m walk to the BW & its activities.
BC/BCV tend to attract families with very young children, so while still beautiful, tend to have a much higher noise level. YC/BC/BCV share a large pool complex, which many love - we find it just too crowded (lounging or actual swimming is just about impossible) & noisy for our tastes.
we've only visited the swan/dolphin (mostly to pick up a car rental, occasionally to eat) - they are not owned by Disney (no DME,
DDP, etc).
all are within a 20m walk (or boat ride) to EPCOT, DHS, and mini-golf.
