If I was going for price alone, I would stay off site. I booked CS previously because it was one of the only resorts available at a decent price. When I go in December I'm staying off site for $46/night, haha, so when I go cheap I go FULL ON cheap.
There is one big thing that this is riding on, and it's how much I love Storm Along Bay. If you've stayed at YC, what are the hours like? I've heard things like it closes at dusk, which in October with the sun setting around 8pm....will not be fun. I know they change frequently, but did you find that it closed significantly earlier than other pools?
