When I think of the resale restrictions, the seemed oriented toward the 2042 expiration having a larger impact.
Right now, the resorts we would want to exchange to are the ones often considered park resorts. BCV, BWV, and RIV for Epcot and DHS (OKW is also extremely close but falls under the drive or bus to Epcot). If looking to avoid boat, PVB can walk to TTC and monorail to Epcot. For MK there is BLT (walk or monorail), VGF (boat, monorail, and recently added walk), PVB (boat, resort monorail, ferry and express monorail from TTC). Also add BRV and CCV for boat to MK. AK has AKV nearby, but IMO AK needs some significant additions to the park.
In 2042, BCV, BWV, and BRV are no longer part part of the O14 resale booking options for anyone. At that point, the O9 restricted resale points can stay at 4 MK resorts, OKW, SSR, AKV, GCV (very difficult), and AUL.
