My mom and brother are talking about taking her RV to Airventure this year. Trying to suss out the options for them and could use some help since EAA doesn't specifically talk about RVs.

Option 1: Reserve an improved spot in Camp Scholler. "Improved" spots with electricity and water are for RVs, yes? You pay from the day you reserve, and they sell out a couple of weeks before Airventure starts?

Option 2: Get a regular camping spot without electricity and water. Likely won't sell out.

Option 3: Stay at an offsite RV park, like Sleepy Hollow.

Do I have all this right? If they reserve a spot on Scholler, do they get to actually pick the spot when they make a reservation? Or are the spots themselves first come, first served?
