It costs $ 20 dollars the entrance. I don't know about the parking lot. I arrived by train (the station is opposite) Access is through the Hyatt Hotel. Before going, check the schedules. During the week I think they open from 4:00 p.m. to 8:00 p.m. On weekends it is from 1:00 p.m.
There is a controlled parking but the day we went it was open and it was free. On Groupon they sell discount tickets
$ 20 entrance fee and $ 9 hotel parking at the end of the street
