Can you buy tickets at the entrance? Or you need to reserve

I bought our tickets at the entrance! It was easy.

We reserved our tickets, but it look like you were able to purchase them at the entrance

Yes

Yes you can but booking ahead is much more convenient and you might be able to get discount if you have coupons 😉

Yes you can

You can but them there , I went on Viator and saved 10% as a first timer.

While you can purchase tickets at the door, it is better to reserve them ahead of time.

Yes you can buy at the entrance

Yes. They have ticketing kios at the entrance. However, depending on your schedule, you'll secure your spot if purchased on line than buying at the entrance where your slot is not guaranteed.

You can do both. Depends on when you’re going. When they’re so busy they don’t let you buy tickets at the door.
