You can reserve at the Pacificorp website...we do not have any first come first serve sites. And the gate to come in closes at 9pm every night.
First come first serve
go to Pacific power parks
They close the gates at 9 pm so nobody can get in after that.
I don't know about getting there at 11, they do have quite hours. And I think that we reserved a spot online
