We have a holiday booked in Croatia for the middle of July. It's very likely we will have to cancel, but not definite yet. I have 70 days left whereby I can cancel and only lose the deposit, after that I am increasingly liable for greater percentages of the total balance. I have travel insurance which runs out on the 31st of this month. I would like to hold off as long as I can just incase things will be OK (I know it's unlikely). Do I buy more travel insurance now just to insure that I am completely covered in the event of cancellation, or would that just be a waste of money? Would it even be valid in the event of cancellation given that COVID 19 is a pre existing event at this point?
