Finance expert Martin Lewis has issued a fresh alert to those looking to jet off in the coming weeks as coronavirus restrictions begin to ease across Europe.
Mr Lewis, who also runs the website MoneySavingExpert, has urged holidaymakers to check their European Health Insurance Card (also known as a EHIC) before they travel.
What are EHIC cards?
The EHIC cards are free to apply for, and allow British citizens to access state-provided medical treatment in the European Economic Area when they travel abroad and have their card to hand.
The cards allow the holder to have free or discounted medical treatment at state-run hospitals and GPs in any European Union country - plus Iceland, Liechtenstein, Norway and Switzerland.
Why has Martin issued the warning?
During a recent episode of his self-title Martin Lewis Money Show on ITV, he said that more than 5.7 million cards are due to expire in 2020.
Speaking on the programme, he said: "Ensure yours is valid before you go away.
"Even if you've already got travel insurance, it's valuable extra protection, even if just for visiting the local GP with a query while away."
How can I apply for a new card?
Martin added that holidaymakers can apply for a new card up to six months before the current one ends.
To do this, visit the EHIC website, or call 0300 330 1350.
The application form can also be printed out by visiting the NHS website.
It can be filled in and posted to: NHS Business Services Authority, European Health Insurance Card, EHIC Applications, Bridge House, 152 Pilgrim Street, Newcastle Upon Tyne, NE1 6SN.
However - it's worth pointing out that you cannot get an EHIC from your doctor or from a post office.
Those who have lost their cards, or if they have been stolen, should call 0300 330 1350, or from abroad call 0044 191 218 1999.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
