I have stayed at POP 38 nights just this year (visiting DD as a CM) and over 120 nights collectively. I think you will be hard pressed to find a resort that has BETTER bus service than POP. There is only 1 bus stop and it really doesn't share a bus (on RARE occasion it may stop at AoA but that is extremely RARE!!) The disadvantage is the bus stop for POP at the parks is 'usually' the furtherest one out. Another possible advantage depending on your room location such as bldgs 3, 4 & 5...they are very close to the bridge and AoA and if you are headed out of a park and see and AoA bus I would not hesitate to hop on that AoA bus and just walk across the bridge to POP. It is a VERY short walk to bldgs 3, 4 & 5!! The AoA bus stop tends to be next to the POP bus stop.
The Food Court....
I personally have not encountered the food court at the hectic times people speak of but... That is not to say they don't exist, but I have yet to witness it!

If I have waited for food, it is because it was a special order. Or there are a few things like the reuben (my DD loved that) that are made when ordered but it wasn't a really long wait, maybe 5 min? Another pro, you have the option of another food court with additional choices just across the bridge at AoA! And you can hop on a bus to a park right from there too!! Or you can stop and eat there before heading back to your room.... POP and AoA's food courts are quite different, so you would have the benefit of two different sets of choices at your fingertips!
I hope that gave you some of the info you were looking for...and good luck with your decision!
