They cannot always promise this, especially when you made your resi seperate. Had you made it together, originally as a Grand Gathering, they couldn't have promised unless it was available at that time. Different folks request different size sites and amenities. How would you like it if the site you requested first(months ago) was given to someone else months later because they called and made a requesta week or two before arrival? Camping is just not as flexible in this way as a hotel might be. I've been to State parks that don't use this common sense and almost had to go home because my camper would not fit in what was left, when I had been promised a more than adequate site.
