I'm a bit concerned about the effects of the recent trend (mass movement?) towards relaxing mask mandates and requirements in the US. Combine that with the new variant that is supposedly even more infectious than Omicron, and the current testing and quarantine policies in many foreign countries, and you have a recipe for an unhappy international travel experience. It seems like the old expression, "Err on the side of caution" is no longer considered acceptable.
Personally, I'm not concerned about getting seriously sick. I consider myself in good enough health and protected by 2+1 shots that I won't suffer serious ill effects if I am infected. But, it sure could put a crimp on travel, if I'm surrounded by many who are unmasked and infected either in an airport, plane etc. prior to or during a tour.
Let's hope the FAA and CDC do not relax air travel mask requirements and that Tauck can continue to keep us in the "bubble ".
