We've stayed at Pop twice and we love it! Like some of the other posters said....it really depends on what you want out of your resort and it looks like you are wanting to save money this trip so I think Pop is a great choice!!

The food court is almost always busy, but they move the lines quick and the food is pretty good.

The rooms are a basic sized hotel room, 2 double beds and they are comfortable.
The only noise we ever heard was if someone came back later to their room than we did...you could hear their door shut. It is a big, spread out resort (most WDW resorts are anyway!), however there are shortcuts (like cutting through the parking lot) if you just look at the map. It's fun to look at all the Huge Disney Deco!
Bus service- they have their own bus, not like other resorts that pick up 2 or 3 resorts. I don't think we ever waited more than 20 minutes for a bus. At park closing time, it seems like the buses come at quicker intervals to get everybody back to the hotel.

We stayed at All Star Movies before, we really did like it, the only draw back to us was the buses because they picked up AS Music and AS Sports as well.
So we tried Pop and loved it!!
Hope you have a great trip!!!
