If you male a reservation at Larkins on the River- they have free valet parking.
The parking deck above the bus station is free. Across from Barleys. Few blocks to walk though to get to Larkins.
Most parking garages will charge you. You rarely can find a parking space after 6 on the street but if you do it's normally free. The best place I found was behind Greenville County Square. It's a little walk but free. You can sometimes find parking at the parking area before you get there off of University Street.
Also, type in Japanese Dogwood Lane. Their is a garage at the start of it ($5 but rarely manned) that is simple access without the mainstreet traffic. Short of valet, probably the easiest.
Yes after 6
After 6
