70% of consumers booking rooms through the Expedia Hotels mobile app or Expedia’s mobile commerce site are looking for travel within a 24-hour period, the travel company finds. Location and price trump luxury. Travelers booking rooms via mobile devices typically choose  hotels with ratings between two and three stars—42% are two-star properties and 37% three-star properties—and within a 10-mile radius of their current location.

Because 70% of consumers booking rooms through the mobile app are looking to travel within 24 hours, Expedia has launched deals available only through the Hotels app. These deals, ranging from 10% to 30% off hotel rates, are available at more than 2,000 hotels in the United States, Canada and Europe.

Nine of the ten most popular destinations for hotels booked via mobile devices are in the U.S., Expedia finds. The top ten include (in order from least to most hotels booked): Paris, France; Chicago, IL; Orange County, CA; Miami, FL; San Francisco, CA; San Diego, CA; New York (Manhattan), NY; Orlando, FL; Los Angeles, CA; and Las Vegas, NV.

The afternoon and weekends are hot times for mobile booking. 37% of flights and hotels reserved via mobile are booked in the afternoon hours between noon and 6 p.m. Friday and Saturday are the most popular days to book via mobile.

“Mobile devices have continued to become an essential part of travel, whether traveling for business or leisure,” says Joe Megibow, vice president and general manager of Expedia.com. “With more travel options than anyone else, and now with exclusive deals just for mobile users, Expedia is making sure that no matter where you are, you can find the right deal for you.”

On a related note, Harris Interactive conducted a study of travelers for Expedia. It surveyed 2,247 U.S. adult Internet users, 46% of whom took a vacation this summer that included an overnight stay.

86% of online U.S. adults who had an overnight summer vacation took pictures while on vacation. Of those vacationers, 58% shared those pictures through social media during their vacation. Vacationers are active social sharers via Facebook. 54% who took photos on their most recent vacation report sharing pictures on Facebook during their trip and 55% report sharing pictures after their trip. Only 9% report sharing pictures via Twitter during their trip, while 7% report sharing pictures via Twitter after their trip. And 6% report sharing their pictures during their vacation via Instagram, while 7% report sharing their pictures after their vacation via Instagram.
