It was pretty bad... About 2-3 hours for kk and almost 2 hours for Nitro. It didn't help that toro was running terrible all weekend with trains getting stuck at the bottom of the lift. Thanks to my qbot I got on a bunch of rides.
Last operating weekend 2 years ago had fights breaking out and nitros line backed up to skull mountain. I suggest not going the last weekend unless it rains and if you do get a gold q-bot. It's worth it!
