I know DLR =/= WDW, but these were some wait times
during a halloween party recently. (Have you been on the NSS thread? People would riot if these were party wait times out here)

And this was early on. Haunted Mansion was 2 hours later. Come the next non-party night the waits were even worse.
By mid-morning Saturday, RSR FP line was at least an hour. Not the line to get on the ride with FP, but the line to get a FP. By noon, you could wait in an 80 minute standby for ToT, or grab a FP for 8pm. (and all of this is in the "light" park). I basically lived at DHS this summer and I can remember maybe a small handful of times wait times were anywhere near that, and there was always a FP available for sooner than 8 hours out.
Add to that the fact that most of the major rides were down at park opening (RSR, TSMM, Screamin') and the fact that you can't get FP while the ride is down, and standby lines were crazy all day.
There is no FP+ to blame out there.
