You do need a reservation yes. Usually timeslots are open and you can get in if you get tickets in person. I would suggest getting your tickets and reservation online because it's faster.
Nah just show up on a weekday and you're gtg
We went on a Friday and didn't have to wait to enter
You can just purchase tickets at the door but it helps to have a reservation.
No you do not need a reservation, I went in late January. You can purchase tickets right at the front.
