If you get therre at about 9:15, go on MF first. If you get there later, like 9:45, there will already be alot of people in line for MF, but Mantis's line should be short. I went 2 days this year, 1 day I got there at 9:45, got in line for Mantis. The next day I got there at 9:15, got in line for Millennium Force. Check out
www.guidetothpoint.com, it has a strategy thing of when to hit each coaster.
