We were there in July (26-31) of this year for our third year in a row. We had requested the 50s, but we were assigned to the 60s building 4 - we were on the first floor facing the lake and the Legendary Years buildings which were never finished. We were in standard rooms, but we were very close to the Hippie Dippie pool and just a short walk from the main hall. This was really a perfect location. I would not want a room facing the pools, but I know others have not a had a problem with noise even then. I think the 80s building is really farthest from the bus stop/main hall, but it doesn't seem that far even. For us, we really wanted connecting rooms, so that was our priority really moreso than location and they were able to accomodate our request for connecting rooms AND give us this great location, so we were very pleased!
The buses are great - the longest we waited was about 15 minutes one morning and that was because we had just missed the first bus out (7:30am for a EMH AM opening - I forget which park). The queues for the buses are not covered but just behind that area is a covered area with benches and lots of people sat/stood there to wait when it was raining one day.
Mousekeeping is adequate, nothing extraordinary. We did get a couple towel animals on our last stay and in previous years we have had window displays with our kids animals hanging from curtains, etc.
Hope I caught most of the questions, if not, let me know!
