When are you looking to go? I've been watching to maybe book a trip next year but only Movies will be available (so far). We stayed there summer 2019 and it was updated, the rooms are like those in POP. We enjoyed it, but it was precovid so things are different. We enjoyed being able to get drinks/food at Music, take any of the All Star buses. If I had too choose though, I'd pick Movies for the updated rooms. So I'm glad it's the one on offer so far. They all had slightly different lunch/dinner menus, with the regular stuff plus a couple different things. My son liked the steak and shrimp at Movies. The pools were fine, of course no water slide like at a Mod or Deluxe.
While we really want to ride Skyliner, I'm not sure if we'd pay more to stay at POP now. I was sure we'd prefer it but we actually really enjoyed ASMovies.
