Hotels are being offered to book at the equivalent price to what they were in 1999 as LateRooms.com marks its 15th anniversary.
The deals were available yesterday (Tuesday) and tomorrow.
The company is also offering £99 rates at four and five star hotels
A competition also gives customers the chance to relive their favourite travel memory by posting a picture to Instagram or Twitter of their favourite break of the last 15 years with the hashtag #TakeMeBack to win a free stay in that destination.
Head of marketing Georgian Crosswell said: “We’re delighted to be marking our 15th birthday by involving our customers in this way.
“We pride ourselves on being able to provide a room for every need, and offering our customers exciting and unusual deals seemed like an amazing way to celebrate our anniversary and reward our customers with some birthday treats.”
