We have stayed at the Pop many times...including busy summer months and Christmas week - and we have never had any more issues with buses here than at the WL or the Poly. In fact, at night's end, in the parks, they often had multiple buses at the Pop stop to accommodate the long lines.
We enjoy the Pop and would return in a hearbeat. We do not "hang out" at the resort, nor do we have small children anymore, but we find the Pop to be the most convenient to the parks of the values - less than 10 minutes to Epcot and the Studios - longest trip is MK at 20 minutes. We don't usually eat at the food court - we get breakfast or night snacks and bring them to the room to eat. My preference, especially in the morning. We do that no matter where we stay. THe times we have eaten at the food court, tables were available. It was noisy, but that would be expected.
I am sorry that they removed the frozen coke machine - but no other resort has them either, as far as I know.
We always stay in the 50's. We don't pay for preferred. I found the regular rooms to be only a few steps away from the preferred, so it's not worth the cost difference.
I don't understand the parking issues. When we parked at the Poly or the WL, we parked much farther from our rooms than the lots at the Pop. My only stays at the AS were without a car, so I don't know about the parking there.
Enjoy your stay at the Pop. I always do!
