No, but is not much to park, less than $5
Parking is not free. Parking is charged by the length of time that you are parked in the parking lot. There is an attendant that you can pay on the way out of the parking lot or you can use your credit card in the automated lane when you exit the parking lot. I don't believe that the gardens provide parking validation.
The park does cost but it is not expensive at all.
We bought a parking pass for $20 unlimited parking. If you visit frequently, especially during special events, is worth it.
No
Just for the first 30min
No, I went last Saturday for 3 hours and it was $8
