I was told only one car was allowed is that true? Usually you're allowed to cars per campsite

I guess it would depend on the cars. I would give them a call. It may be that only one car is included in your entrance fee and that you would have to pay another fee for an additional car.

The way the campsites are set up in the RV area it would be difficult to park more than one vehicle. Also, in the RV area there is an overflow parking lot that would facilitate 8 or 9 vehicles.

Not sure but usually you could park additional cars at restrooms.

3 car permits per campsite

You are allowed two cars at the screen shelters and camp sites. They all have double parking. So limit is 2. At the day swimming area it does have limited parking but not a actually limit per family

I don't know about that . Don't park close lol
