We have our wedding August 13th, 2020 in the UK. But the thing is my fiance and I live in the Czech Republic, and 80% of our guests will be coming to the UK from Europe and the US. So with corona virus we are thinking international travel is not going to be possible, or even if it is by August, no one will want to fly. I've spoken with my family who is coming from the US and only three of them would fly out, my parents and my sister. Our insurance won't cover travel circumstances such as the travel ban, and my venue isn't letting me postpone the wedding as of now because they said they can't accommodate everyone to reschedule for next year. Does anyone have any advice?
