You didn't say what you were looking for in a resort so I'll just give my opinion on the 5 choices. I have many "favorites", it depends on what we're doing on that trip; I voted for BWV. Disclaimer: we own BWV but have stayed at AKV (Jambo), BWV and OKW, and non-
DVC rooms at WL and BC.
Animal Kingdom Villas:
Beautiful resort, a bit far from the parks (except AK and BB), pools are nice, great restaurants. Great for a relaxing vacation.
Boardwalk Villas:
Great mix of location (EP & DHS) and plenty of restaurants close by; enjoy walking the Boardwalk. I'd pick either a room with a view of the Boardwalk

or a standard room to save points.
Wilderness Lodge:
Very nice relaxing resort, quiet, remote except for MK. Not much of a view from the rooms. Easy boat ride to MK, Contemporary, GF and Poly. The path from WL to the boat dock is exquisite!
Beach Club Villas:
Very close to Epcot (and DHS), Stormalong Bay, plenty of restaurants close by. Not much of a view from the rooms.
Old Key West:
Large rooms, love the boat to DD (take it every day), quiet but not that far from parks. Easy parking next to each building. My DH's favorite resort.
My suggestion is to pick one to stay at and visit the others. Each resort is an experience in itself!
