The cheap "lead in passes" caused a two class system... I have the money, so I can push in with paid fasttrack. I don't have the money, so instead of queueing for twenty minutes, which is acceptable, I have to let a thousand people ride before me, because they have paid an extra fifty quid to push in. The problem was nothing like as bad when passes were more expensive. Cheap passes caused massive capacity issues as well. Booking should be easier when there aren't a million discounted pass holders.
