If you don't mind walking, park at the Cuvier Club (reception location). It is 2 blocks inland from The Wedding Bowl (ceremony location). Should you opt to try to park at the ceremony site, there is street parking that is limited to 2 hours (that is STRICTLY enforced) until 6pm (and make sure you cramp your wheels to the curb).
There will be no public restrooms at the ceremony! The closest public restroom within walking distance is at the Children's Pool area. About a 5 minute walk north. Please note: The local hotel, the museum and the private homes do not offer their restrooms, in some cases, not even in an emergency! There will be restrooms at the reception location following the ceremony.
No alcohol or smoking is permitted per park regulations.
