Being recently retire I like it, but as recent memory serves me, this is definitely not designed with the working family in mind. Rush out of work, hurry home, throw the DW and kids in the van, and drive like a knight on a crusade (if everything was packed the night before) only to find your favorite spot taken by some geezer (which I am now)!
But from my point of view (now), to reserve a specific site, based on inter net info is frightening. To make a reservation and have the pick of the park when I get there...priceless!
