FYI,
Majority of divers (27/30) were from USA. So Nautilus charter a big Greyhound-type bus from ABC to haul us back to San Diego.
The remaining three guests, two of them were from Mexico City and one, my cabin mate, was from Italy. Those three, non US residents, flew in & out through Tijuana airport and required to get Covid test before flying home. The rest of us didn’t need to get the Covid test for going back to US by land.
Going home without needing to get a Covid test is a blessing for us when you see how long the line was to get back to US via San Ignacio land port. We were stuck in that line for 2 hours, plus 2 hours of travel time. So, most of us arrived back in San Diego around 9pm and had to stay overnight there, before flying home on the next day.
You can see that Americans are about 90% of the clients. Without us the trip may not be happening. Fortunately most of us have been fully vaccinated too.
No one tested positive of COVID-19. We were in COVID-19 free environment.
