Do we have to buy tickets online or can we buy them when we get there?

Either way, but online is best since they give you a timeslot

Yes online

You can do it on site, but online was convenient in order to pick your time.

Doesn't really matter

Bought tickets at kiosk at entrance to zoo

I believe that the zoo encourages an online purchase in order to assign an entry timeslot. This is one of the measures they incorporate to socially distance the volume of visitors during the ongoing pandemic.

Online

Buying tickets in advance online is highly recommended. Make sure you have your barcode ready to scan for the entry

All guests, including members, must make advance online reservations, and an additional advance ticket purchase is required to visit BIG TIME.

You can do both .

You can do both options.

U can buy them on line or if u want buy them there

Either way

We got our tickets while waiting in line then skipped the line and scanned the phone. Enjoyed the Zoo.

Online. Best way!

It is best to buy ahead of time because they issue you a time slot.

You can buy either way. I recommend online.
