We have thought about staying elsewhere but we love AKV at KV but we do not like the multiple stops of other resorts so we always stay at home. Just recently stayed at KV and the lodge for a meeting after my stay and all I can say is we saw far more AK buses come than anyone else . We rarely waited at KV more than 5-10minfor a bus. On the return waited about the same. If you are at the poly you are going to have to take that 20 min ride to get to AK. We rode the BC bus when the monorail was down to get to Epcot and we must have waited at least 25 min for the bus. Might have been rare but it did happen. Plus at AK there is only one stop.
Just got home and we loved it, my wife who's been to Disney 20+ times says its her new favorite resort, and switch out reservation for may from bwv to bcv if it opens up. Lol
