Casitas or Cabanas is good. Rather than requesting a certain building, you can request "close to El Centro" is that is where you'd like to be.
I'm a big fan of POR (I consider that to be our "home" resort) and POFQ. CSR is really not more spread out that POR, but the set-up is different with the central lake in that you can see the whole resort from one place unlike at POR where you may take meandering paths from far flung areas of AB.
This will be our 2nd stay at CSR, also by default as I requested POR or POFQ, but we're not disappointed at all about getting CSR. It's a lovely resort and we do like it a lot! The atmosphere is very relaxing, and my dd thinks it has the best pool slide.
The biggest 3 things I miss about "home" is the boat to DTD, Bob Jackson's show and being able to walk to it, and the fact that there are hooks on the wall in the other rooms and for whatever reason CSR does not provide hooks.
Favorite things about CSR are the lovely atmosphere (I think it's the most "deluxe" moderate), Pepper Market is a great deal on the
DDP, the pool slide, and the sliding door to the bathroom area is nice. You can also get your mugs refilled at the pool bar, though I think the pool bar is not open in the evenings. I really like the bus service at CSR in that the buses ALWAYS stop at the stops in the same order, so you can hop on any park bus to get to El Centro. The bus stop order at POR is random. I like the organized bus service at CSR! I think you'll enjoy your stay, and it is fun to try something new. Perhaps you'll have a new favorite resort.
