YAY!!! You are going to LOVE POP!!! Don't forget to take time to walk over the bridge to AoA. You DS will love it and so will you!
Here is a picture of the bus stops. Each park has its own little chain line to get into. There is also one for the water parks and DTD. The buses come about every 10-15 min depending on how crowded they are, sometimes faster and during the middle of the day when there are less guests going to the park, it may be a little longer. The drivers have radio's on their bus and they communicate with the other bus drivers to let them know how crowded the lines are. The buses at POP have been great in our experiences and we would never think of using any other mode of transportation. During our last trip in September, we rode several of the accordion buses, were it is almost 2 buses in one

so they hold A LOT of people! Don't let the lines scare you!
If you are in a preferred room, you will be closest to Classic Hall and I love a morning walk to Classic Hall for coffee. A small coffee pot is fine but not needed.
At POP you will have direct to the room access. If you do on-line check in, customized your MB, you have a credit card on file and your cell # or email address, they will send you your room # before you get there. You will be able to go straight to you room when you get there. The 2 buildings in 60's are building 4 & 5. The top 2 floors are 3 or 4. If you room # starts with 43xx, 44xx (Play-doh building 3rd floor or 4th floor) or 53xx, 54xx (Moglie & Balu building, 3rd or 4th floor), then you know that you got one of the room that you requested. So you should be good to go.
Here is a picture of the resort with the room categories highlighted for you. You can see the preferred view highlighted in yellow. The majority of the 60's is preferred so hopefully you won't have any trouble getting your request

You are always welcome to go to the front desk if you don't get your requests and kindly ask if they have something in your requested area but honestly, in our 8 previous stays at POP, we have ended up LOVING every room we have stayed in.

for the perfect room!!!
