Freiden8 - you've never stayed at a moderate, how can you comment on this?
POR definitely has a large fan base, so there is lots to read about it.
All the mods are good for different reasons.
I have stayed at CSR twice so will comment on that. CSR is the biggest mod and some people don't like that, it seems too big, I like it because I never feel confined! I also don't feel that walking to El Centro from anywhere at CSR is too long, but if you've got youngun's, it might be a hike, so request a room closer to El Centro.
CSR has a lot of recreation, sand volleball court, large pool plus three quiet pools, arcade, health spa, poolside bar and snacks, bike rentals, and more. It's a good resort to just hang out at for an off-day from the parks.
It's not close to anything (IMHO). You can't walk to Epcot, there's no boat to MGM, so you rely on WDW busses - but there are a lot of them and they are a dedicated route - meaning you dohn't stop anywhere else!
It has a business convention center - good and bad. More "suits" walking around, less kids (still kid friendly). They have suites there too (only mod with suites).
I love the southwest theme! It just relaxes me the instant I get there! Then again, I'm from the mid-atlanic, not New Mexico! If I lived in the southwest, the theme might seem a little boring.
Figure out what you want in a resort and look at all of them - I can't wait to stay at the others, but CSR has a special place in my heart.
