we do have express w our RoF but we only used it for Poltergeist with a 30 minute posted wait and ST which had a 50 minute posted wait.
my family doesn't rush or commando tour or anything. We tend to stop by too many stores, we also waited until night fall before really hitting up the houses but we truly found houses a walk in even if posted at 15 minutes.
it might be that last night was not originally going hold an event.
anyway, if I were the type to really tour, use stay and scream, last night I think I could have done every house twice.
