We went in April of this year and my FIL has same issue. We requested handicap rooms to be sure this was a non issue
We were put in connecting rooms in Mansion building. Pagen or such.. I know you cross bridge and first building on right
Anyway, all the mansions have one elevator in the middle of them. It can still be a hike though from the bus stop to the mansion you are staying in.
Now the bellstaff was great and my FIL took got rides all the time to our mansion (basically around back where you could park). If you are drving, then non issue for you.
But just know that even with the elevators, it can be a hike..
Oh and even though their room was handicapped it connected to our double bed room with us and kids.. so not like we had to have a 2nd handicapped and put out someone else that needed the room
