Dan. Just saw this update in their brochure. The added preboarding info address most all my concerns about possible false positives. I feel much better about this after reading this...
“Our job is to keep our guests and crew safe. Now more so than ever during the COVID-19 crisis. Please ensure you arrange for a PCR or antigen test within 7 days of boarding. We will also be providing complimentary antigen testing before boarding. This is required for your safety and that of our crew. If you test positive in Cabo, we will arrange for a medical diagnosis and if the virus is active, you are required by law to go into 14 day quarantine. Per CDC guidelines, if you test positive and are asymptomatic it is recommended that you get a second test. A false positive could occur, in which case you will want the retest results. If you do test positive, we require a doctor’s note or medical report confirming the diagnosis, and you will receive a full credit towards a makeup trip on a later date of your choice. All of our crew members are regularly tested, both on and off the boat. Please read our COVID-19 FAQs” here.”
