We both camp, but there are plenty of hotels in Clinton. There is a free shuttle that will deliver and pick you up from any of the Clinton hotels. It runs from about 7:00 AM until about 9:00 PM.

For any other potential first timers to Clinton:

You don't need a car to have fun at the fly-in. We have a free shuttle van that will run you all around Clinton.
We can bring you to some of the touristy things around Clinton if you want. (American Pickers, Clinton Saw Mill Museum, etc.)
Some folks do rent cars. If you want/need a car, it's best to rent early. There is only one rental option in Clinton and that is Enterprise Car Rental.
There is a Super Walmart in Clinton. We make several runs there each day. You can get most anything that you forgot or didn't want to pack. You can also get beer and wine! Soft drinks and ice are available at the airport for nominal cost.

For early bird arrivals:

We go out for breakfast and lunch each day before the fly-in starts. Once it starts, breakfast and lunch are available at the airport. Breakfast is free, lunch is priced modestly.
We usually grab dinner at one of the local spots. On Tuesday, we usually do Mexican. (Except for Uncle Eddie)
