Tried it with Kayak,, Travelocity, Expedia, etc to test it. This is legit! No matter what booking engine I use, The Guestbook Extension saves big money and gives cash back. Never booking a hotel without The Guestbook Extension again!

I'm very frugal when it comes to traveling...I always search for promo codes, discounts, or coupons to save money. With The Guestbook Extension, I don't have to do any of that! This is perfect for hotel bargain hunters like myself.
