They are not crowded
I didn't reserve my tickets but I know you can go anytime you want. So the reservation is probably just so you buy your tickets early and you don't have to wait on a line. But I think you can use those tickets at any time you want.

I was late by 20 mins and they let us in.. you can try going Early
