CLE is my "home away from home", so I don't park at the airport often. But, after parking at a variety of airports over the years, I think the airport parking facility is very reasonably priced. And, there is the additional advantage this time of year that it is covered so you don't have to clear the snow off your vehicle when you get back or walk through snowdrifts or cross a wide open expanse of lot with 30 mph winds giving you a windchill in the minus numbers. If you're only gone a couple days, how much could you save anyway? Now, a 2 week trip, maybe the savings are worthwhile. I'm sure they're there, but I've never spotted a private lot at CLE.
