Enter July 30th and 3 nights (if you are staying the same number of days as us). The number of people in your party doesn't mean anything so just pick whatever. Then pick the kind of stuff you are bringing to sleep in and unless you are a senior or disabled, scroll to the bottom and click submit.
If there is a bunch of red text saying that the lot is unavailable, just click the link that says 'Click here to select another site'. And thats it, you can see which sites are available.
You probably want to know which site we are in but I'd rather not have the entire world know where we are staying so just e-mail me or msg me on msn and if I like you I'll tell you which site we are on.
