If you manage multiple campgrounds, you will be able to move reservations between them. 


On the edit booking page, click "Change Campground" 



When moving the reservation, the current one will be cancelled and refunded, and a new reservation will be created for the campground they are being moved to. 



Choose the campground you'd like to move them too, and then continue the booking process as normal. Select the traveler, which sites, dates, add number of adults, etc... 



Finally, payment will need to be taken again for the reservation.
