I love prontohotel and since I discovered it, I book all of my hotels through it. Unlike some other sites that aggregate different booking travel websites, prontohotel keeps them nice and neat in one page. I heard about prontohotel through a friend and just last friday I purchased four nights for 3 rooms at NYC through this site for an upcoming family trip this December for my cousins wedding! It was very simple to find hotel deals, hotel information for the period I would be traveling. This site makes it so easy to compare many booking websites, thousands of hotel rooms, it takes a lot of the work out of finding the best hotel in New York for my trip for the best price, saving more than 40% I managed to get all my bookings at about half the cost thanks to prontohotel!
