London hotel prices during the Olympic Games are at least twice as high as last year, according to a study.
Prices for booking in March this year for stays in August are reproted to be more than 100% up on the same period last year.
The average price of a hotel room in London will be £213 this summer, according to the study by Hotels.com.
The company’s annual survey of 142,000 properties in almost 20,000 locations suggests room prices worldwide rose by 4% in 2011 on the previous year.
Prices went up in more than two thirds of destinations popular with UK travellers, with increases in 69 of the 88 city or resort locations analysed across the world.
Hotels.com president David Roche said: “Price volatility in 2011 meant UK travellers found it more expensive to stay in the majority of their favourite destinations abroad.
“A variety of factors, including currency movements and a growth in corporate travel, pushed up prices at a time when many consumers were already struggling to pay their bills at home.”
Room rates fell 2% in Asia last year but rose 8% in the Pacific, 5% in North America, 4% in Latin America, 3% in the Caribbean and 2% in Europe and the Middle East.
The economic crisis in Greece led to a 10% fall in hotel prices in the country.
