Good morning! We stayed @ CSR in Sept. 2011 and are on our way back there in 17 days. You are going to get a lot of opinions on CSR, some good and some not so good.
Our pros and cons were:
Pros: 1) The feel of the room! To us, it felt more on the deluxe side. We loved the sliding doors that separate the bathroom area from the sleeping area. The colors are warm and inviting, and it just felt very comfortable to us. The queen sized beds are a must for us (we are a tall family). 2) The main pool area. The pool is large and the jaguar slide is lots of fun for all ages. We thought that the theming @ the pool was great! Plus, on our last visit, they had pool side movies each night (I think a lot of the resorts do this now), and they had a small campfire where you could roast marshmellows and make s'mores. 3) The bus service! Now, I have only stayed onsite 4 times, but in 2011, we never waited longer than 10 minutes for a bus to/from any park or DTD. Maybe we just were lucky, but we never had crowded buses either. 4) Close to most major parks. Okay, so a lot of the resorts can say this. But, it seemed that it never took longer than 10 minutes to get to EPCOT or HWS, maybe 5 minutes to AK and Blizzard Beach. MK probably takes 15-20 minutes to get to by bus, but DTD does take awhile... think it was 25-30 minutes? But, being close to 3 of the 4 major parks was a perk for us.
Cons: NONE! Okay, at least not for our family.
A lot of people will tell you that if you get "stuck" in the Ranchos section, it's not a good thing, because it's the furthest from El Centro. Our family actually requested the Ranchos in 2011, and we have requested Ranchos 7B again for this coming trip (hoping we get it!). We are not a family to rely on the main food court/shops @ the resort much, so even if we did have to venture that way, it was about a 10 minute walk each way. We were close to the main pool, 2 bus stops, right next to the Ranchos quiet pool, and the laundry facility. Other folks may tell you that the resort is too big. We didn't mind the large size of it, as it felt like it was relatively quiet. Others will say that it being a convention resort is a con. However, there are other convention resorts on WDW property. We didn't notice the folks attending the convention when we stayed, and it meant less people on the buses to the parks!
I'm sure no matter what you decide that you and your family will have a magical vacation! Good luck deciding!!
