Replying to Car hire

I think the address for the bus station is N JOHN YOUNG PKWY 32805

That address is missing the building number -- the full street address is 555 North John Young Parkway.

If you're unable to find good information online, Greyhound does have a published phone number for the station, and the phone agent may be able to tell you about rental car options -- call +1 407 292 3424.

I think you should be able to google the various US rent-a-car firms and find out. Along with that also determine their hours, whether they pick you up, etc. Then go to google maps and locate these various places.

In US English the normal term is car rental or rent-a-car.
