Martin Lewis has explained how you can save £200 on your holiday even after you’ve already booked.
The trick involves keeping an eye on hotel prices to see if they drop before you’re due to travel.
If your current hotel booking has free cancellation, then you can cancel it, get your money back - and then rebook at the lower price.
MoneySavingExpert Martin said: "If the price of your hotel has dropped and your booking allows free cancellation, simply rebook for less.
"Check the latest prices on comparison sites Skyscanner, Kayak, and TripAdvisor - and keep checking before you go.”
One woman replied with her own success story, and said: "I saved £200 when the price dropped two days before travel."
Of course, this doesn’t work if your hotel booking charges you to cancel.
Always check the terms and conditions of your booking first to avoid being stung by unwanted fees.
Martin previously issued ten urgent holiday warnings for anyone planning a summer vacation in the next few weeks.
One of his tips was to check the expiry date on your passport.
Since the Brexit transition was completed, British travellers can no longer visit the EU on a passport that's about to expire.
Under Schengen area rules, your passport must be less than 10 years old on the day you enter, and valid for at least three months after the day you plan to leave.
Many other countries - including the United States and Australia - require you to have at least six months left on your passport.
If you do need to renew your passport, be aware of long processing delays and get your application in as soon as possible.
You should also watch out for roaming fees and check if your health card has expired.
Vodafone, EE, Sky, Three and Voxi have all reintroduced the controversial charges for customers who are abroad in the EU.
Each firm is now charging £2 a day for when you use your UK allowance - calls, texts and data.
You may be able to cut costs by buying a bundle, depending on how long you're away for.
Meanwhile, the European Health Insurance Card (EHIC) is being replaced by the Global Health Insurance Card (GHIC).
These cards give you access to state-run hosp i tals or GPs in EU countries for the same price as a local.
If you have an existing EHIC, it will remain valid until the expiry date runs out - after this, you'll need to apply for a GHIC card.
