I suggest if you're a local and looking to be the last riders before the change, don't wait until the last moment to ride. I had no problem riding POTC the night before it's last day of operation prior to the change with no waits... but the next night was a poop show and there were long lines and breakdowns and people couldn't ride.
Same thing happened with Universe of Energy. You don't HAVE to be the last to ride. Your memories from the day before are just as good. So stupid.
