That will depend on the Park’s/attraction’s policy. Ocean Park, for instance, scans the voucher provided by Klook and then you are good to go. But for Disneyland, you need to scan the QR code on the voucher to print the actual tickets at Disneyland’s Automagic booth.

You can contact Klook directly for terms for each attraction.

I saw your article about attraction ticket in Hong Kong, I would like to ask about Klook.com, is it after booking I will get the e-ticket or I need to exchange with the real ticket? Please help to answer. Thank you 🙂
