According to the Expedia/Egencia Mobile Index, 60% of the 9,642 travelers surveyed said they "would be unwilling to go on vacation without a mobile device." A full 63% said they sleep with the device by their bed while they are on vacation, and 28% take the extra step of carrying an extra battery pack. (Lest they be unpowered for even the shortest period of time.) "We have found that travelers are using mobile devices at every stage of the travel process, from researching and booking trips to capturing and sharing the travel experience," Aman Bhutani, president for Brand Expedia Group, said in a statement. "Just because a traveler can use their device to read work email and stay connected to the office, they also believe it improves the quality of their vacations," he added.
