No. No showers and the bathrooms are early cleaned.
Are there showers in the restroom
Around 10 to 4 might vary by season
I believe their there mid morning till mid afternoon. Or at least that's the times I been through there and I see the staff there.
I am not sure. I usually stop on Tuesdays and the visitor center is closed. Restrooms and vending machines are available. Some outside seating and tables are also there. A good place to rest and stretch.
