They for sure need to do something about it, especially since that exit services more than just BGW.
Maybe an express lane for active members, open up the exit lanes for active members entrance.
Issue I see here is that there's going to be a lot of daily pay that don't understand what that is and go in that line holding it up anyways.
I've given some thought to this in the past, and here's something I would go to:
1) England would no longer be VIP parking. It would be member parking with exception for the kennel. I would reconfigure Busch Gardens Boulevard by that area to have an entrance for members only, and only put in an unattended 3 gate plaza that's scan and enter. Then you keep the road for kennel payers.
2) Major change: Reroute the tram road to use the access between Germany and Italy parking lots with a turnaround back there. This gives the ability to widen the toll plaza by a few booths. Again I reroute exits to be a cross over from the lots to 64 as a bridge over the entrance area. I know this was done not too long ago, but it's needed for the more widening I would plan, but you have the space for this because of losing the tram turnaround. And instead of exiting to 60 this way, you put a direct exit from the parking lots to 60. This would give a few more booths.
3) On busier days, I would send an alert to the people that bought tickets early with a text or email - Scotland Lot is accessible via 60 by way of exit 242A, and if they park there parking would be $10 as opposed to whatever they pay at the main toll booth. This would encourage people to exit the highway sooner and park at a different spot to alleviate toll gate stress.
4) France as the VIP lot could use the opening along 60 to BGBoulevard as an entrance for pre-purchased parking in VIP via eastbound traffic only, again encouraging use of exit 242A to get to this spot. Because this would be for prepaid only, there's no need to have a booth there, you can just post up someone under a tent with a hand scanner, and have someone just stand there to direct traffic for anyone that decides to try to sneak in that way.
