A New Website Helps Travelers Find the Cheapest Hotel Room.

The website, which offers hotel deals and then monitors them for price changes, is the newest player in the price-hacking travel game.

Websites like HotelTonight have long tried to solve the dilemma of when to book hotel rooms to get the best rates. Online travel agencies like Booking.com and Hopper have added price protection programs for the same reason. And still travelers complain about how hard it is to find a good deal on a hotel. Now a new site, HotelSlash, joins the quest, promising discounted hotel rates to members and a tracking service that monitors reservations for price dips.

Were travel hackers at heart, said Jonathan Weinberg, the chief executive and a co-founder of HotelSlash. He also runs AutoSlash, a platform for rental car deals that will track reservations and tip off travelers to any decrease in prices so that they can cancel most car rental agencies allow free cancellations and rebook at the lower rate.
