TourismUKFinance 34% of Brits let parents-in-law foot the bill for joint holidays But over two-thirds of children-in-law still complain about the trip, says iCarhireinsurance.com -- A new study by car hire excess insurance providers, iCarhireinsurance.com, has found that one-third (34%) of Brits have previously let their parents-in-law foot the bill for a joint holiday. The research, which surveyed 1,000 UK residents who had holidayed with either their parents- or children-in-law also revealed that just 8% of people have covered costs for their parents-in-law on a joint trip. Despite often getting a free or reduced cost ride on family holidays, children-in-law are more likely to complain about the trip than the ones footing the bill. Two-thirds (66%) of those who travelled with their parents-in-law listed annoyances that occurred on the trip, compared to just 55% of those who were travelling with their children-in-law. The most common annoyances were: * Not getting enough alone time: 30% * Having to compromise: 29% * Disagreements with in-laws: 17% * Costs: 13% * Arranging childcare: 11% -- Over half of survey respondents (52%) said that these annoyances erupted into actual arguments while on holiday. Almost one-third (31%) said they argued with their in-laws on half of the days of their trip, and 6% argued every day. The most common causes of arguments were: * Eating arrangements: 41% -- These arguments aren’t putting everyone off holidaying with their in-laws though. Less than one-third of survey respondents said they’d be unlikely to take a trip with their in-laws again. Most (82%) recognised that holidaying with their parents- or children-in-law did have benefits. The most cited were: * Family bonding: 55%
