They are only going to answer during season. April 15th if I'm not mistaken is the official opening day.
Im not sure if they answer or not..we also had to send people down to make our summer site rentals..they just started taking reservations..we were there on the first day..and they already had nearly 200 reservations to make..we were #87 out of 173 that day ..it can be a tough park to get into..or the sites you may want..
My Family and I had to drive there because we had the same issue. It is very hard for some reason. Try to contact them by e-mail.
