I need to park at airport from Friday afternoon until early Tuesday morning. Where should I park and what is the cost? Is there shuttle from parking to airport all hours?

Long-term parking, check airports website for long-term daily rate. I believe it's $9 a day but I could be wrong. There is a shuttle at all hours of the airport operation. Very easy to do. Ads about 15 minutes of extra-time.

Value Park is good. They do have a shuttle. Last I was there it $8 a day for parking. If you have a business card with some companies, such as Cincinnati Insurance or Great American Insurance, you may get a discount.
