I'm just pointing out the GP are not going to be pleased when they find out after they've waited an hour already for a 5 hour wait that they can't really do anything else unless it's a walk-on. They aren't going to understand the "Well technically you're waiting in line" thing, They are going to say... "I'm not in line, I have waited an hour, I have 4 hours to go, let me ride some damn slides."
Me, personally? I would not touch a slide that displays the current wait the Volcano slides are touting. Unless it's the one slide I've yet to do, and that is the reason I am coming to the park that day.
