If you're going to use a trailer (tear-drop) you'll need to get in line when it starts or you'll find it very difficult to maneuver when everyone is trying to get into the onsite area all at once.
Generators are forbidden on site.
It's not so bad if you have a camper, but anything you have to tow will be a hindrance.
It would be better for the little ones than a tent though as it would be less noisy at night.
There's actually two separate areas of the onsite. One is for tents only and the other is for tents and vehicles.
I'm sure you won't have any trouble selling the vehicle pass if you decide to tent camp.
