Difference Between Instant Booking & default booking process?

Instant Booking lets Hosts pre-approve hours and direct the guest confirm they're coming (and checkout). Once done, the pool/backyard address and access information is shared. The icon signifies if the pool/backyard offers instant booking.

In the default process, you request a pool/backyard, the Host reviews the request and approves or rejects it manually, and then you confirm if you will be attending that booking.

Guest can cancel an Instant Booking reservation as per the pool /backyard’s cancellation policy.
