Wow ... There's nothing like being rude to a new poster who came in and *gasp* had the nerve to speak about his (her?) opinion.
What is wrong with you people? *EVERYONE* is entitled to their opinion, whether you agree with it or not.
I happen to be a local, and frequently don't get the parks until the later afternoon. We work, and have kids in school. Which means on days when we do choose to head out, we have only a couple of hours max to do attractions. I'm sure you out-of-towners are jealous of that, but if you don't like it, move here like I did. Problem solved.
Perhaps you aren't considering the fact that the OP probably has a job to go to, which means 8pm may be the earliest feasible time to hit the parks. When the lines are long, it means you just don't have time to ride things if you go, especially if FPs are all gone.
I personally think FP is a waste, and if you don't like my opinion, oh well - I'm still as entitled as you are to share it.
