Having friends who live in Spain, and France, and hearing first hand about the situations there, I can't understand why anyone would want to travel there for a holiday under the current circumstances. Just because the UK is doing a good job with their vaccination programme, it won't give anyone 100% immunity, and with these other countries not doing so well with getting their vaccines underway, I'd rather put my holiday on hold, until they sort themselves out.
I'm really no longer bothered about 'going on holiday' per se ... I'd just love to be able to visit my daughter, and my son/DiL, and granddaughter, who all live in different countries. It's been 15 long months since we've seen them. But I know we're going to have to be patient for a while to come.
