High demand for domestic breaks has seen a claimed 38% spike in late summer bookings in the last week at Hoseasons.
The self-catering operator citied warmer UK weather combined with delays to European travel for the bookings surge for lodges and parks over the same week last year but did not disclose actual numbers.
Cornwall and the east of England are proving most popular, with bookings up 41% and 53% respectively.
Sales through third parties, including travel agents, rose by 17%.
The news comes a week after police warned motorists heading for the Continent to expect weeks of delays at Dover.
Hoseasons managing director, Simon Altham, said the increase was particularly impressive following a fifth record summer in a row last year.
“Great weather at home always has a positive impact on our bookings, but demand has been unprecedented over the last few days as customers weigh up their options for the summer,” he said.
“The ability to grab one of our great late deals online, pack up the car and then arrive at one of our fantastic family-friendly destinations within a few hours is clearly resonating with the holidaying public this year.
“People want convenient, safe and secure getaways and we are a great value option.”
