Yes, the website states you do, but they weren't checking the reservations at the entrance.
We had pre-arranged station but I think you could buy tickets at the gate also. But it will be higher
Yes!
You could make a reservation to get in the park but we came there late one day in the park was already full so it doesn't really matter if you make a reservation or not because they still sell tickets at the gate for the people can get in
Reservations are highly recommended as is arriving early.
