Any time you are attempting a booking with a Request To Book campground, your credit card will be pre-authorized immediately for the price of the potential purchase. This is a pending hold, not a charge. However, if the reservation is approved (and this can take up to 24 hours), then the pending hold becomes a charge. In this type of scenario, the notation on your credit account will say "pending" next to the amount.

If the reservation request expires or is not approved, then the pending hold will be released, but that can take up to 72 hours.

If you have booked an Instant Book campground, the charge is immediate upon submitting payment.
