It starts at the airport...

21% paid more than £10
You could also get stung if your luggage exceeds the allowance:
Astonishingly, over a third (34%) had to pay extra because they exceeded the weight limit
30% paid over £10 for exceeding their baggage allowance

Don't forget your travel insurance
45% of travellers admit to going abroad without travel insurance.
Travel insurance can cover you against medical costs, theft, loss of your valuables, cancellations, delays and most other things that could go wrong on holiday.
However, you will only be protected if you get a policy with the right level of cover.
While you are abroad
Once you have arrived at your destination, you still need to be careful, as you could be hit with all sorts of unexpected fees and charges:

43% were asked to pay for a safe deposit box at their hotel
Other unexpected costs include car hire excess charges, expensive taxis and using air conditioning in your room.
Whatever services you use abroad, ask how much you will be charged first and read the small print.
Even worse than these fees is the danger of street crime and theft: 23% claim they have been the victim of pickpocketing whilst travelling in Europe.
29% know someone who had fallen victim to a scam at least once while holidaying.
