There are many hotels near these exhibits but my son and I chose to go camping. There are several campgrounds in the area. This is a beautiful campground called Camp Shore Campgrounds, it is mostly set up for small to large campers/RVs with electrical hookups but you can also pitch a tent and there is a boat ramp that launches into the Ohio River. You can watch huge barges going down the Ohio River. Also a very nice chlorinated swimming pool.
