According to data complied from a Travelclick survey, leisure travel will be about the same as it was in summer 2010, while business travel is expected to expand greatly this year. You may be surprised the find that the people waiting in lines at the airports this summer won’t be families wearing flip flops and Hawaiian shirts, but business travelers with briefcases instead.

Travelclick, a New York company that provides e-commerce products and services to the hotel industry, found that the number of business travelers renting rooms is up by about 8% over last summer, while those renting rooms for leisure will remain about the same as in summer 2010. “This summer, business travel has been and continues to be strong as the U.S. economy continues to recover,” said Tim Hart, executive vice president of business intelligence at Travelclick.

If you are among those business travelers heading to a corporate housing destination this summer, maybe you can squeeze a snorkel and some suntan lotion in your briefcase – along with your laptop and meetings schedule, of course. After all, it is summer, right?
