Big Mike....you missed the point. Someone posted referring to Rick Steves as "The Boss:. He's not the boss. (When you have to explain it.......)
I'm glad to hear so many people are going to wait until the virus is gone/there is a vaccine/there is no more social distancing, etc. I'll probably be going sooner than all of that which means many of the sights I want to see won't be as crowded.
Will I have to make some changes? Sure. I'll bring masks. I'll check out distancing at restaurants more or get food to go. Perhaps it may mean renting a place with a kitchen and doing some cooking. (I like going into supermarkets anyway to see what the locals buy.) I might stay in more chain hotels since they are issuing cleanliness guidelines that must be adhered to. Smaller, individually owned hotels may be hurting for money and many not want to spend the extra amount to truly disinfect a room.
Tours will be fine. People will want to travel. And many of those inclined to take tours like the idea of someone else doing all the work. All they have to do is show up and be led around.
And in terms of Covid-19, it seems that much of Europe is doing better than we are in the USA. I'm hunkering down in a college town that hasn't seen students since the end of March. However, they are scheduled to return in less than a month and the town is very concerned. They believe the virus will increase drastically.
The decision to travel or not travel is up to the individual.
