There are limited hookup sites available at Camp Scholler, but they are fairly expensive and you have to pay from the time you reserve until the end of the show. They are power and water, no sewer.
There is a 24 hour generator area, but it fills up quickly. There is also overflow for the 24 hour generator too. One downside of this area is there are many people who use open frame generators - they are noisy and smelly compared to the inverter types. So if you are hoping to sit outside your RV and enjoy the sights and sounds, you may be disappointed.
We have done both the 24 hour area and the hookup area. We are hoping to do the hookup area again this year. Much more pleasant in my view if you are willing to spend the $$$. I'm a cheap airline pilot too, so I understand
