Is there ample handicapped parking for a high school graduation?

Yes

Ues

Yes in the garage

Yes, but in the garage

Yes, park in garage

I don't know my company did a job there

You may be able to find it, but it will likely be at some distance from the event space. When I went, one lot had filled and the next auxiliary lot was a deck a long ways away on foot. No stairs, but still took a while to get back to the event center

I would say you would have to get there early. There are a lot of people attending graduations with handicap tags or placards.

I wouldn't say ample, get there early is your best bet

No, the was a big problem when I went for a graduation 2 weeks ago
