An official will affix a dated holografic decal to the inside of your vehicle windshield. The second step is to obtain your passage tickets for yourself, and your vehicle from the ferry office ticket window in downtown La Paz. Few tourists are knowledgable of La Paz, so I'll give generic directions to the office of the ferry boat company. This is signed with directions to Cabo San Lucas or San Jose del Cabo. The ferry office terminal is located five blocks down Cinco de Mayo, on the far left hand corner.
Parking is crowded.
You'll be better off coming here early in the morning. Your passengers must show the ticket agent their valid tourist card, before their tickets will be issued. This is your final boarding notification. Three O'Clock in the afternoon is the standard assembly time to wait for the ferry to start boarding. Your ferry boat may NOT be the one nearest the terminal parking lot buildings.
