Arthur's Blog: An App Called Hotel Tonight is Emerging as a Device of Enormous Benefit to Travelers

Most apps bore me. Whenever friends extract their iPhones and Androids from pocket and purse and gaze endlessly at their dozens of apps, I don't feel the slightest envy. The apps I've downloaded are three: Flashlight (for deciphering menus in dark restaurants), Angry Birds (out of curiosity as to what the excitement was all about), and Frommer's Travel Tools (which performs an unquestioned function; I'll soon be downloading some of Frommer's Day-by-Day Guides, too).
But another app -- Hotel Tonight -- is emerging as an enormous benefit to travelers. For the 40 biggest U.S. cities, the 15 largest airports, and London, Toronto and Vancouver, it lists special discounts (as much as 70%) on unsold rooms for the very night of the day you are consulting the app. I've heard of people who have scored major coups of pricing by using Hotel Tonight to obtain a sharply-discounted, last-minute room; and as long as the people behind the app work conscientiously to consult scores of hotels on a daily basis, this particular app can perform a major service.
So I now have four apps--and am not a total Luddite, am I?
