Oh my god Glitch01, I am doing the same thing next week. On Monday I will be at Coney Island and PKI (my home park). On Tuesday and Wednesday I will be at the Point, and Thursday at SFWoA.
Anyway to answer the post, we stayed at the Roadway Inn last year. It was not the best, but it was pretty cheap. I didn't care because who needs a really nice hotel when they will just be sleeping there.
