Lived there 10 years ago, but just flew in there last March. We love it. It is nice and small.....you can either park right our front, or you may need to go "long term" to save money, but it is nothing on the scale of Detroit or Cincinnati.
Lines not too long for security. Inside, there is a Sbarro, a Starbucks-like coffee thing, but you may want to bring a lunch or snacks from home as there isn't anything else to choose from. A very small bookstore and I am not even sure if they sell gum.
Not many gates; maybe 20 total, split into two sides? When you return, you won't be waiting long for your luggage!!
Watch for construction right before you hit the airport on I-70; you can take that straight in, by the way. Once you cross I-75, the airport is the next exit off I-70.
Have a great time!
