My husband's sister lives in Tuscany and her son (his nephew) lives in Milan and is getting married in Italy in his fiancee's little town in the mountains near Perugia on 30th August. My husband's sister has invited our whole family to the wedding and wants to know numbers so she can book the hotel. What with another lockdown just started, Brexit, passports, health insurance, will we have had the vaccine, will it be safe to travel in a plane, what will the situation be with Covid in August, still wearing masks, social distancing etc. etc. I just don't know what to say to her and it's more or less impossible to decide now. My husband told her on the phone "yes, we'll be there". I think it's a ridiculous thing to ask just now and it's the last thing on my mind. What do others think? Should we say yes we'll go and if things don't improve she'll have to cancel?
