Right now, Hipcampers can only book one site at a time. To book multiple sites at the same listing, Hipcampers must go through the booking process multiple times in order to do so.
We hope to allow Hipcampers to book more than one site in one transaction in the near future, but in the meantime, it must be done in separate transactions as separate bookings. You should receive a booking confirmation for each site, as each is a separate booking.
