I'm not sure if this is the right forum but couldn't figure out where to put it. For those in the SW Ohio, eastern IN area: Through 25 Jan Groupon has a special for Park-N-Go at DAY, $15 for 3-day valet parking or $20 for 4-days. Normally it's about $10/day (though I often use it at that price especially in winter. Their self park is nice, too - better than the airport operated lots). Days must be used consecutively and only one voucher per "stay".
