Based on current requirements for COVID testing within one day prior to return to the US, we would plan to get tested in San Cristobal the day prior to our flight from San Cristobal (which would be the same day as our flight to the US). Are there places to get tested in San Cristobal with results available within hours? Are they available Sundays and or evenings? Is there a site that has this information and keeps it updated? Thank you.
