Thomson and First Choice are calling the day “Sunshine Saturday”.
Following the Brexit vote, the firms are predicting a rise in all-inclusive bookings as Britons seek value from their holiday experiences.
Thomson and First Choice are expecting to see more than 27,500 customers book a holiday for 2017 on Sunshine Saturday.
For 2017, Thomson said it had already seen all-inclusive holidays make up 53% of bookings for the coming year.
The holiday companies are expecting nearly one million holiday-seekers to go online or visit their high street stores this Saturday, with bookings predicted to peak in-store at 2.07pm specifically and online at 4.02pm, with Thomson Gateshead Metro Centre expected to be the busiest store on the day.
A new mobile booking record for 2017 is also predicted to be set. Thomson and First Choice are forecasting more people than ever before will search for and book their holiday on a tablet or smartphone.
Forty three per cent of the online bookings made this Saturday are expected to be made via these devices, up 4% versus last year.
Short and mid-haul beach destinations such as the Balearics, mainland Greece and the islands of Corfu and Rhodes will continue remain firm favourites with Brits, according to Thomson, however far flung, long-haul hotspots are expected to top the wish list in 2017.
With 77% happy to travel more than nine hours for their break, many more people are expected to book exotic holidays in 2017, with Vietnam, Cuba’s Cayo Santa Maria and St Lucia topping the list of predicted ‘hot’ long-haul destinations next year.
Thomson Cruises will also see long-haul a focus for winter 2017 with more ships based in the Caribbean than ever before and new ports of call added.
Thomson Airways is estimated to fly more than 107 million miles to 92 holiday destinations.
Andrew Flintham, commercial director for Thomson and First Choice, said: “With plenty of great deals on offer, we’ve already seen a rise in all-inclusive bookings for 2017 as customers seek value for money from their holiday experiences following the Brexit decision.
“This year will see Brits travelling to more exotic destinations such as Vietnam and Cuba, with our multi-centre and city break holidays making long-haul destinations more accessible than ever before."
