We have just about come to the conclusion that we don't want to do any more group travel.
It's a shame because we have two trips scheduled (and deposits paid) for next summer/fall. Both will most likely be canceled (at hardly any cost), and that's a shame because I really wanted to go on both of them.
It's still possible that we'll do a little group travel in the future when things are back to normal. But it just doesn't appeal to us right now, for a variety of reasons.
I honestly feel bad for the tour operators, who have really been kicked in the butt by the current situation (like many other industries), but why should we do what isn't comfortable for us?
All the offers we keep getting for cruises, land travels, etc. are so tempting, but with only a few exceptions we have come home from those excursions thinking mainly about how much we would have enjoyed doing our own itinerary instead of what the tour operator offered. In some cases, there is no choice but to go with a group (examples would be Galapagos or Antarctica) but in most cases it's simply a matter of convenience.
Giving up the convenience of letting them take care of the details gives you the advantage of going exactly where and when you like, which I think is probably well worth it in most cases.
