We stayed here for three nights in total. Loads of signs saying beware of theft but we did not see any incidents. We stayed with our vehicle whilst there as we only slept there. Toilets were ok and it was pretty quiet at night.
During the day we drove down to the marina carpark which is free parking between 0600 and 2200hrs, and explored from there. We used Uber cabs once that was very reasonable.
Alcatraz was also a great trip.
