If you are frequently on the road or a spontaneous traveler, but you haven’t picked up the awesome little Hotel Tonight app yet, then it’s definitely time. Why? Because Hotel Tonight just added a new feature called Look Ahead that will make it even handier than before.

First off, if you’re not familiar with the Hotel Tonight app, here’s a brief description of some of its features and how it works. Hotel Tonight offers great same-night deals on hotel rooms. These deals don’t go live until noon. At that point, you will receive a notice listing hotels that are available in the area you are interested in as well as their costs. Hotel Tonight also provides a list of amenities for each listing and breaks down its hotels into the following categories: hip, luxe, solid, basic or charming.

With its new Look Ahead feature, Hotel Tonight has added another dimension to this app. Now, it allow you to see the estimated rates for hotel rooms as well as availability in a desired area for the next seven days.

Let’s say, for example, that you are thinking about visiting your brother in New York in a week. Your calendar is wide open so you can go any day. One of the determining factors for your trip is the cost of your room. In the past, you might have called around to several hotels or plugged in different dates into a search engine. Now, however, all you will have to do is tap the Look Ahead feature on the Hotel Tonight app to see a forecast of hotel room prices and availability.

To create these forecasts, Look Ahead considers such factors as large events and conventions in the area and the weather as well as historical booking data. In addition, if there is a large event — say, a cheerleading competition with hundreds of teams in the area — it will inform you of that fact so that you can decide on whether or not you want to book now or take your chances later.

Currently, the Look Ahead feature will only be available in New York City; Washington, DC; Miami; Chicago; Dallas; Las Vegas; Los Angeles, San Francisco and San Diego, but plans are to make it available in more areas soon. Although, Hotel Tonight is available for iOS and Android users, the Look Ahead feature is currently only available for use on iPhones. The app is planning to release a version for iPad and Android users in the near future.
