My wedding has 80% of guests flying in (all domestic though). Our catering has a minimum and we are already on the edge of that. We'd have to pay for all that catering anyway.
If this coronavirus scares people from traveling, I might consider inviting some local friends that I didn't invite. It would be last minute invite if this happens, maybe 1-2 weeks before the wedding. I don't really care about the wedding etiquette. I'm just going to be honest with those friends, some of them I met after I started wedding planning. If they want to come and hangout, that's awesome. I don't expect gifts from them. If they don't want to come, no problem either. What do you guys think?
