Wow! A refurb? POP is one of the new (ish) resorts too! I want to give it a try next year. A refurb makes it all the more appealing!
We have stayed at ASMu and loved it. Only downfall is that the All Stars are a bit out of the way of some things. For example, we make several evening trips to DTD during our stay and it was a bit of a trek. POP is a bit more central in that it isn't at any of the extreme corners of WDW.
