@MonteCristo also keep in mind that the Fast Lane and Fast Lane plus don't go into effect until a park is open for all guests. 

The only time that I ever would want to get a Fast Lane plus pass would be to ride Steel Vengeance and Maverick continuously just because they're such good rides

I think it would be the parks goal to not have any stand by lines or very little ones if at possible.  If your standing in line your not spending money in the park and some queue lines take up massive amounts of land.  Think about this going to the the entrance scanning your season pass, ticket or cell phone and the kiosk tells you the link is currently 45 minutes and come back at whatever time.  Return during a certain window and scan your pass and be seated on the ride with 15 minutes.
