ERT to me is worth it because you are in the park getting to areas in which you want to start out your day. I am a roller coaster enthusiast and cant get enough of it. I knoq how hard it is to get on rides like FH and FoF in the middle of the day so I always go get Diamondback a few times and then right before the park opens, my son and I head to the part of the park where FoF is and get ready to attack those. I have found that early in the season, there is plenty of time to get on The Beast as many times as you want and Vortex as well.
My goal this year is to ride every thrill ride and coaster before the end of the day. Anyone think that is possible?
