Help! Where can I park and get to appointments on time in Rochester?

My husband has an appointment at the Hilton building at 9:30 and one at 9:45 in the Gonda building. I will need to drop him off, park and walk to the Hilton building. He has a couple more appointments after that. Where should I park? Damon parking ramp? How far is to walk to the Hilton building. We have not been there before.
