Yes I think
If you're referring to the RV park, yes, with military ID, you can "stay" there on a transient basis. For the marina, you'd have to check with the marina office during regular daytime business hours to obtain a slip there so you can stay longer than a week or more. Please note that the marina is not set up for transient visitors but instead for long term slip rental.
I believe you can as long as you show your military ID... It is a beautiful place!
