Families are willing to spend 13% more on their 2017 family holiday compared to last year, according to research by ATOL.
A survey by the holiday protection scheme found a family of four are now set to spend an average of £3,133 on their annual break this year.
But the research also found unexpected holiday costs mean families end up spending an average of £536.80 more than they budgeted for.
ATOL’s research revealed that 61% of families struggle with budgeting on holiday.
UK holidaymakers are most likely to get caught out by having to pay for additional food and drink outside of their original booking, and being charged for withdrawing money abroad.
Parking charges, additional car hire costs, and airport transfers and shuttles were also high on the list of extra costs.
Andy Cohen, head of ATOL, said: "Holiday costs can mount up quickly, while you’re enjoying your holiday, making it very easy to overspend.
"Our research also showed the unexpected can happen, and over their lifetimes nearly a fifth of consumers (18%) have had to pay for replacement accommodation and a sixth (16%) have had to pay for new flights."
The survey of 2,000 UK adults who holiday abroad was conducted by Mortar in March.
