Since I'm camping in a tent I have an inflatable mattress that needs electricity to plug it in order to inflate it, where can I get the electricity to do that? Or do I have to bring my own generator?

You have the option to choose a place to camping that have a energy station and water dispenser in the place that you'll decide. That's one of the best things in ginnie springs.

You can inflate at the front office or you will find power at the bathhouse at the main spring parking lot. FYI ... For less than 20 bucks u can buy an inverter that plugs into the cigarette lighter/charger port in the car.

They have an air compressor on sight. You have to hold your mattress on top of your car to bring it back to your camp

You can inflate that up front where you rent floats.

They have full hookup site with power. If you get a primitive site near a light pole they will let you plug a cord in but you have to bring a screw in plug adaptor for a light bulb. I hope you know this is a party spot. Very loud & noises. No peace & quiet @ Ginnie. Big drunk fest.

So sites have electricity

They have fill stations
