As a solo traveler, I can definitely say that I'd stay at CSR again! I loved it! The fact that there's usually at least one convention going on helps you not stick out quite as much. The ground are beautiful! I stayed in the Casitas section, building 3 and loved being as close to El Centro (the main building) as I was. I had a bit of a hike to the theme pool, but I like that it's pretty evened out...if you've got a hike to El Centro, you're closer to the pool and vice-versa. There were some parts of the Ranchos section that seemed a little isolated, but walking around the main path I never felt unsafe. I got food from the Pepper Market to go a couple of times and it wasn't bad.
Again, I have never stayed at the Contemporary, so I can't compare, but for theming and stuff, CSR is definitely the top choice in my book.
