Sunday Times example - To rent a car for two weeks in July from Barcelona airport the excess would be £800. "It would cost £15 a day or £210 for the trip to waive it through Alamo. However, iCarhireinsurance.com will cover the excess for £2.99 a day or £39.99 for an ANNUAL policy."
Other Sunday Times' Holiday Money Saving Tips
Flights - Make sure you do your sums as a scheduled airline could end up being cheaper than a budget airline due to all the additional add-ons charged by the budget carriers.
Parking - Always book parking at the airport in advance. You can save £88.40 by booking ahead to use the long stay car park for two weeks at Gatwick airport under its Summer Special offer. It costs £75.50, down from £163.90. Potential saving: £180
Travel money - Never buy your holiday money at the airport. Order it online from specialist companies. See Moneysupermarket.com for the best deals. Do not take your usual credit or debit card with you on holiday, as most impose a charge for cash withdrawals as well as a foreign usage "load" fee. Take a prepaid card, which you can load with money before you go and then use as you would an ordinary debit or credit card.
Cut mobile charges - Always switch off data roaming on your phone and try to use your phone only to text rather than call.
Travel insurance - Do not automatically accept the insurance offered to you by your travel company when you book, as you could end up paying well over the odds. Shop around instead.
