As AZmermaid said Columbus weekend is busy. Also look at when Gay Days are. We went in Oct 2012 and were there for Columbus day which was also the end of Gay Days. All the rides had Loooong waits. 90 minutes for BTMRR, 40 for Pirates ect. Also look at school schedules for CA, AZ & NV as they tend to get weeks off in the fall for break. Since it is a small resort stuff like that effects it greatly, kinda like Jersey week in WDW. Did have to waitlist for some nights but they came thru within a few weeks.
