Weary of the unpredictability that comes with a last-minute vacation booking? You’re not alone. But HotelTonight, the always pioneering app for travel procrastinators, is coming to the rescue with a new feature called Look Ahead, intended to facilitate so-called “planned spontaneity.”

Debuting in a handful of the app’s major cities—New York, Los Angeles, Miami, and half a dozen others, with many more rolling out soon—the feature will offer a seven-day estimate of inventory and prices in a particular market, using a proprietary algorithm that factors in local events, weather, and historical data from HotelTonight and other booking engines.

Also on the calendar: notifications for upcoming concerts, conferences, or sporting events that might sway prices (say, Fashion Week or the NBA Playoffs), and a heads up about special packages that may be on offer (think romantic perks on Valentine’s Day, or value-added incentives for low-volume weekends). Pro tip: check the app a few days ahead of your booking to get a sense not just for the prices and inventory, but for the hotels you might be able to choose from.
