I think we have our trip to Provence from last year carried over to this July (we cashed in our trips to the Far East and the US, I wasn't optimistic about the airlines being around to honour any vouchers).
I doubt it'll happen as planned. I'm not about to book anything else, though admittedly it would be nice to go somewhere. I confess to stretching the rules, we'll usually drive somewhere in the countryside at the weekend for a walk somewhere pleasant and not busy.
Personally, I'm less bothered about international travel and holidays, it would just be nice to go to the pub or a bar, to the cinema, concerts etc. again.
