As you can see here on the POP map below, the preferred rooms (highlighted in yellow) are all the closest to the transportation/Classic Hall.

The only preferred rooms that are a tiny bit further from Classic hall/transportation is the back side of the 60's. It is still not far and it is closer to the bridge to AoA in case you want to walk over there. A preferred room in the 70's or 50's is going to be your quietest since there is no pool around the preferred rooms. 60's preferred is in front of the kiddie pool and won't have as much noise as the main pool but still may be a little less quiet. A 4th floor room is also going to give you more quiet and a ground floor room is going to help you avoid elevators/stairs. Do you have a preference on which floor? This may help decide on a recommendation.
I would DEFINITELY check close to transportation-this may get you closest to the end of the building which will get you closest to classic hall/transportation.
When you are choosing your 2 requests, you can mark off lake view, 80's section and 90's section since there are no preferred rooms that meet those requests.
You will not get a king bed with 3 people booked in a room so no worries there. There are not alot of king beds at POP and some are reserved handicap accessible and the others are requested enough to be filled. This is the official POP disboard thread that gives you tons of great info and pictures

Hopefully this will give you a better idea of what you may want to request.
Personally, I would choose ground floor (not having to deal with the elevators gets me that much closer
) and near transportation but If you have a theme you prefer and don't care which floor you are on, you may want to choose 50's, 60's, or 70's and near transportation.
I hope this helps and please share what you choose and what you get when you check in at POP!
