With popular bookings including Spain, Greece and some of the Caribbean destinations, holiday planners were making the most of the final few weeks of beautiful weather.
One family was overjoyed to be booking a holiday again, but they were soon hit with the news of the quarantine, and a little too late.
Peterborough Matters reader Susan Fleming, who lives just outside the city, not only learned of the news as soon as she landed, but as she is a travel consultant, she also had to spend her first day abroad contacting customers about the changes.
Susan, her husband and her son are currently staying in Playa del Ingles, Gran Canaria.
She said: "We arrived on Saturday, July 25, and discovered the news as soon as we landed. We were really shocked, but luckily due to mine and my husband's job, it wasn't too bad as we both work from home.
"The only thing that concerns us is our son, we aren't sure how he will be affected. He is self-employed and is selling equipment to protect against Covid-19, he also works raising money for investors to invest in property. Although we're unsure what will happen when we return, we're trying not to stress and enjoy our holiday."
Susan continued: "It's lovely here, but considering it's peak season it is very quiet, the hotel we're staying in is only around one third full. A lot of the hotels are shut, as are bars and restaurants.
"Very few people are wandering around, but the vibe hasn't really changed too much. People have a very 'it is what it is' attitude about it, but a lot of people are worried about how their work places will take the news.
"We are due to return on August 1 and we are hoping we don't get called back early."
The government said the quarantine rules would apply to people returning from anywhere in Spain, as well as the Canary and Balearic Islands.
A spokesperson said: “The Joint Biosecurity Centre together with Public Health England have updated their coronavirus assessments of Spain based on the latest data. As a result, Spain has been removed from the lists of countries from which passengers arriving in England, Scotland, Wales and Northern Ireland are exempted from the need to self-isolate.
“Protecting public health is our absolute priority and we have taken this decision to limit any potential spread to the UK.
“We’ve always been clear that we would act immediately to remove a country where necessary. Both our list of quarantine exemptions and the FCO travel advice are being updated to reflect these latest risk assessments.”
