We'll be at SSR, BWV & a surprise (to me

Mod.
CBR:
Lushly landscaped, lovely. People do complain CBR is 'spread out', we see it as a plus. Use the little bridge to take a short cut to the Customs House.
We like being away from the larger pools & food courts for a more peaceful feeling. As a yougster, our DS really loved the pirate ship themed pool.
The on site store was well stocked, the restaurants we did not try this time out, but we've liked in the past. IMHO, there's more food choices at CSR.
CBR Mousekeeping has been excellent in our experience & check in a breeze. Say 'hello' to CM Patricia (from Massachusetts) at check in if you see her--she's so bubbly & helpful!
Last year for the 1st time, we tried CSR & loved it, too! It was full, but it certainly did not feel like it.

The resort's restaurant choices were excellent & we appreciated the landscaping & themeing and, like CBR, the very convenient parking. The pool looked super!
We have stayed at POP & ASMU and will again.
DH felt the room in the Broadway section of ASMU was a hike, and he's not a slouch. However, he does run himself ragged in the parks so maybe he was just extra beat.
As a Value, we like POP.
The 90's section is a short walk to the food court & buses. Yes, you'll notice the difference in room size. We have 3 grown people in our room & can't imagine many more. The landscaping, tidy & colorful, isn't as detailed or lush as the Mods. We do enjoy the playful themeing & I can see how the young at heart, as well as children, would really get into the big icons!
JanB hit it on the head.
Also, if possible, spend yr 1st couple of nights at the Mod or Value, as
Merryweather suggested~
