The LODGE,  can be reserved 1 rolling year in advance.  Based on the actual date of calling in to place a reservation.  Some indicate it starts June for the following year.  It also includes what might have come available in the current year, due to a cancel.

It comes with access for up to 4 people.

The LODGE policy differs from  camping reservations.  Lodge reservations open up in June for the following year.

Whereas, Camping reservations start Feb 1st for the current years season.

At this time, all reservations for the LODGE must be made via telephone.  To date there had never been an on-line system to reserve the Lodge. These phone numbers differ from those at the “camper” office.
