Interesting point about the parking situation in downtown. With garages like Jefferson sitting nearly completely empty (yet staffed, fully lit and operation for the small amount of people that park there), you'd wonder if the city couldn't extend some kind of discounted parking incentive for businesses moving into the core.
Seems like a no-brainer, but maybe the issue of the parking costs is being overstated.
That said, the parking costs was a major reason the company I work for moved out of downtown Orlando in February of this year. We left, emptied 3 floors of the Wachovia tower at Central & Orange and moved our 200 employees to brand new building by Millennia. As a resident of downtown, I wasn't happy with this, but parking was costing like $30k/month or something.
