And I thought it would be quiet!

[stifle]

They tried FP's for Crush once or twice, but apparently it didn't work out like they wanted to, because there still isn't an FP for it.
The single riders line even goes up extremely in waiting time lately.

Was there March 12th, 205 minutes for Ratatouille!

FastPass at Crush's Coaster doesn't work because the capacity is so low. Only 12-16 guests can ride at a time (3 or 4 shells with 4 guests per shell). They can't send the shells out any faster because they could crash into one another (and in any case unloading and loading guests on that ride is organised chaos already). The principle of FastPass is that a limited amount of the ride's capacity is set aside for FastPass guests throughout the day, but there's already so little capacity on Crush's Coaster that they would make the standby queue even longer whilst still having given out all the FastPasses for the day by 11am. So guests would be less happy rather than more.
