I’m in Italy and I’ve just come back from an unworldly, glorious once-in-a-lifetime week on Lake Garda. Very few people, socially distanced restaurants, mostly outdoor activities, self catering and own transport.
However, to an international tourist I’d say it depends on your type of holiday.
Air travel is still risky and you’re traveling with high risk passengers. The UK is behind Italy in R rates. Say no more. Next week hand luggage in lockers should be allowed, so yet more jostling on board. I wouldn’t do it.
Museums are fully policed for mask wearing. We managed two hours and were gasping at the end.
Shops are masks and hand gel. Busy streets and markets are advisable, too. Best to avoid.
The only public transport I considered was an open top boat trip. They are running at one-fifth capacity (one seat occupied with four around it bearing “no entry” stickers). Family groups can sit together obviously.
DD is 14 so well able to cope with restrictions. She knew it would be a low key holiday and understood that Gardaland theme park etc. were not happening. Fractious toddlers would have made it a pretty stressful holiday.
So, the options are there. Italy needs tourism to survive financially and has opened its borders. It’s up to you to decide if you should go.
But remember YOU are the one moving from a higher to a lower risk COVID country.
