Here's the link again to the general reservations info page.
The reservations phone line number is (877) 444-6777.
This is the site for booking
Lower Pines sites.
BUT ... I just found out only 2 sites can be booked under one name. So, even if we can snag 4 or 5 sites, we need a different person's credit card for each transaction.
Any volunteers?
At 4 people per site, 4 sites will allow for 16 people. A 5th site would be required for a capacity of 20 people.
