The room renovations are all fabulous, and the resort is 100% renovated.
In terms of room location...
I've stayed in the 50s section, the 90s section, and the 70s section. Booked Standard each time.
50s was nice, fairly close to the main hub, and has a quiet pool.
90s also had a quiet pool - even quieter than the 50s in my experience - and while farther away from classic hall, is a quick walk across the parking lot to the buses, which I liked a lot. (A lot of people don't like walking through lots, but I've never minded. Felt like a shortcut!)
I most recently stayed in the 70s section, which is the quietest area IMO since it doesn't have a pool. We were in the Mickey Phone building and it was probably the shortest walk to classic hall and the food court. I'd probably request to stay in the 70s section again in the future.
