Maverick opened in 2007, well before the hype of social media and it's a completely different type of ride, different type of trains and restraints, different type of load/unload process, etc. I'm not even sure how you could compare the two.
I'm going to assume that there will be a *LOT* more people heading out for Steel Vengeance in the first couple of weeks of early morning ERT than there were for Maverick. I stand by my initial guess of "one." Thinking that if you are there first, you'll get one ride in, and by the time you get that one ride in, there will be an hour long line that would have built up while you are riding. And if you're not there first, you're in that hour long line...
So yeah... "one" is a pretty educated guess.
Thank you.
