The number of domestic overnight trips taken in the UK during the first quarter of 2011 increased by 5% compared with the same period last year, according to VisitEngland, the national tourism agency. Leisure travel was the main driver, with an increase of 6% in holidays taken in Britain, and 7% more holiday trips than last year taken in England between January and March. VisitEngland said that the increase in domestic trips had generated more than £170m additional expenditure across the UK, with the overall growth for the quarter coming from increased volumes in January and February. A spokesperson for VisitEngland said: "During the month of March there were 8 million domestic tourism trips in Great Britain, an 8% decrease from 8.7 million in March last year. This could in part be due to the Easter Holidays starting later in April this year compared to 2010 when, in some regions, they started in March, and the prospect of a double bank holiday."
