I'm a newbie and yes, I realize that there are already 2 threads dedicated to "Fast Lane". Please bare with me as I have looked through a lot of those theads already. Many of the posters have mentioned how nice they were and how the enjoyed the park much better with a pass. My girlfriend and I are driving down from Columbus this sat and I have bought the Fast Lane passes for both of us. Question is this: How much time do you actually save? If the line for The Beast is 90 minutes long..should I expect 30 minutes? 15 minutes? Just a lot of people seem to be saying they either like it or not but not giving a lot of specifics. I expect to be flamed but I am grateful to anyone who can give me an honest answer.
