Online travel shopping service, Yapta, announced Friday that it has launched a new hotel price tool that will allow users to track and compare pricing on national and international hotel rooms. According to the company, users will be able to choose the hotel they're interested in and then sign up to be alerted when rates drop. The site checks the hotel prices daily and compares them to find similar properties. Once a customer's specified threshold of affordability is reached, they can be alerted to the price drop and acquire a room. The tool is available now.
