Here's the thing about the reservation system. Before the apocalypse, I had the flex pass, so I had to reserve a day (or two) in advance. I couldn't reserve another day until I had either used or canceled one of those two reservations.
It honestly wasn't an issue. But the problem now is, the higher level "magic key" allows for more reservations at one time, which is not very magical for other guests. Everyone should be limited to 2 reservations.
When I was at the park for Star Wars Nite last year, I gave in & paid for the stupid lightning lane to ride "Runaway Railway" before the event since I hadn't been on it yet. I didn't like having to pay an extra $20 for a ride when we used to get the MaxPass for a reasonable price. Still prefer the old fast pass (or single rider), but it wasn't as bad as the lightning lane upcharge.
