It's almost that time of year again - you're either looking forward to the summer holiday you've already bagged or you're looking to book somewhere in the next month or two.
Either way, sun-seekers will soon be heading off in their millions to bask in the glorious summer weather across Europe and further afield.
But as always, Martin Lewis is here to make sure yours doesn't turn in to a holiday nightmare with some vital advice he says is a 'warning for millions' of Brits heading overseas.
Lewis, who founded the Money Saving Expert financial advice website, also regularly appears on our TVs and social media for his ITV1 and ITVX show The Martin Lewis Money Show Live.

And in one of his episodes last year, Lewis spoke about a simple but essential thing that we all need to have if we've already booked - or are about to.
What do you need to do ahead of your holiday?
Lewis explained: "Okay, this is a warning for the millions of people booking holidays at the moment.
"And I need you to understand travel insurance is not just to protect you when you go away.

"I want you to get your travel insurance 'ASAB'."
ASAB? Those who have watched before will know Lewis means 'as soon as you book'.
So if you're booked your holiday your next immediate thing to sort should be travel insurance if you didn't have it in place beforehand.
What happens if you don't?
He explained: "Every spring, I get one or more emails or contacts from somebody who says something like - 'I've just been diagnosed with a very serious form of cancer, or another equally severe illness. I booked my summer holiday, I'll be having my chemo in the summer, so I won't be able to go. I've spoken to the airline; they won't refund me. I've spoken to the hotel; they won't refund me because I didn't book it flexibly. What can I do?'.

"And I say well, your airline ticket isn't faulty. I mean, it's still available, so you don't have rights there.
"Go to your travel insurance. And so many people say to me ' haven't got my travel insurance yet, I was going to get it before I went'."
How much does travel insurance cost?
Travel insurance costs vary depending on many factors like age, health conditions and if you want it to be an annual policy or for a specific trip.

You can also get group insurance for families.
"Please do not be the person who sends me that heartbreaking email this year," Lewis said.
"If you booked a holiday, travel insurance can be as little as £9. Get yourself on a comparison site, get yourself some protection so that if you can't go on the holiday, you're covered – not just if something goes wrong when you are on the holiday."
