We stayed at POP last Oct. in the '60s building - we didn't have any other requests. Buses are usually crowded (especially in early morning and especially especially for the early-opening park o' de day & at park closing).
It was a good stay - the bellhops were very helpful, the lobby is an interesting place to hang out, the pools are good (at least the Hippy-Dippy Pool I experienced), the Generation Gap Bridge is OK, the arcade is good, the food court is good (great food at a decent value), the shop is OK (I don't like shopping so I'm not the best judge in that regard).
I have a construction project in N. Orlando that I had to check on during our stay and getting out of the park-to the car-and out of WDW wasn't as bad as I had feared (it took about an hour total from when I left the family at Studios to when I hit the Interstate).
