Obviously you love WL and my post is not meant to tell you not to stay there and try CSR but rather for people who are open to that possiblity.
First of all, CSR is large. However, you do not need a car and getting from point A to B is not a pain for most people. We stayed there with my elderly aunt. She had a hip injury she was recovering from and she did just fine. For that matter, I have stayed at SSR (even bigger than CSR) with that same aunt and my mom. My mom was recovering from surgery and chemo. She did fine. These large resorts have shortcuts and you see a varieity of ages and mobilities getting around them just fine. At CSR there is no section that is further than a 10 minute very leisurely walk to the main area. We were in Ranchos, I think the furthest section to the main area and it took us around five minutes. And all sections of CSR have a quiet pool and bus stop very nearby. Unlike resorts with only one bus stop, you never have a long trek to or from the busses and your room. Very convenient. There are definitely people who will find CSR too large. I think some of the walks to the main pool are around 1/4 mile. To me and I think most people, that isn't a big deal. If you look at the CSR thread, I believe there are some facts and statistics to show the exact distances we are talking about. But I do know that if my aunt could get around that resort on a cane when she was still hurting, most people will find it very navigable. As long as they know ahead of time that it is a multiple building layout (likes so many other WDW resorts).
CSR is a convention resort however the chances of you seeing nothing but a bunch of "suits" is minimal. We stayed there during a huge convention, never saw a suit. This is not a typical convention atmospherwe. And BC and CR are also convention resorts. CSR is still at WDW, it doens't feel stuffy or all about work and not play. And the upside to those conventioners is that while they are at their meetings, they aren't at the pools or using the busses to the parks. Honestly, if it were not for being a disboard member, I'd have no idea this resort is a convention resort.
Again, my post is to merely point out some things out for the people who do have a desire to stay there. Its large but not overwhelming (and lets face it, you walk at any Disney resort even the one building set ups at WL and BW), it doesn't feel like a convention resort based on my stay and visits there (we are
DVC and we pool hop to CSR most every trip and spend at least a whole day there enjoying its beauty, pool and Pepper Market).
CSR isn't really meant to compete with WL or the deluxe's. Just as WL can't compete with some of the other deluxe's since its not on the monorail or walking distance to a park and the rooms are smaller than say the rooms at the Poly, CR or YC. However, since its cheaper than those deluxe's it has a lot to offer for the price. Just as CSR does for its price.
I just think its so hard to compare these two resorts! Of course CSR will come out the loser since its not a deluxe if and you compare it point by point to WL. The issue is that for $700 less, can CSR offer a resort experiece that can hold its own. I think it can. But for loyal WL lovers, it won't!
I see a lot of "I wouldn't stay there over WL" but if you needed to save money, you might. If you just compare it and say "money's no object" that's different. But to me, $700 is clearly a lot of money and I think CSR can offer quite a bit besides the savings. JMHO.
