Masaki Okazawa from Merkle posted on Twitter a test Google is trying in search to show hotel prices for a specific hotel over a specific date range directly in the search results. It looks like a bar chart that shows prices for the hotel from today going through the next month, with the average price listed on the left.
Here is a screen shot from Masaki:
I assume when you click on it, it takes you into the Google Hotel search features. This lets you search fairs by multiple booking web sites and change your dates, and much more.
