- Standard cancellations usually have a $10 cancellation fee. Customers can generally cancel before the check-in date online.
- Late cancellation rules differ by stay type.
- Individual campsites: cancelling after 12:00am local time the day before arrival usually means a $10 cancellation fee plus forfeiting the first night's fee.

- Modifications are allowed before the cut-off window, but fees depend on the change. Changing to dates completely outside the original reservation dates may trigger a $10 change fee. Extending or shortening a stay that still includes original dates usually has no change fee, though refunds may depend on timing and facility rules. Switching to the same type of campsite for the same dates usually has no change fee, but price differences are charged or refunded.
