At our local park it is fairly normal to wait over an hour for the bigger rides if you go on a weekend, which is when I've normally gone.
It was actually surprising to me when I started reading on the DIS that people would refuse to wait over 30 minutes a lot of the time.
It really depends on the ride. Between FP, rope drop, and less crowded EMHs it doesn't seem like there are a lot of instances outside of peak times/holidays where it would really be necessary to wait over 30 minutes. If I really wanted to ride something, an hour seems reasonable enough, but it would have to be a situation where we would not have the opportunity to ride it later with a shorter line, or we would just really have to want to ride it and have nothing better to do than wait.
I like having a plan, so such circumstances wouldn't arise to beging with, lol.
