Cheapest Hotel Booking Websites? The Unofficial WSO Hotel Booking Thread!

Hey guys,

Associate told me they'll be sending us on more and more trips soon and also I'll be making a bunch of personal trips around the country in upcoming weeks.

SO, being the money smart jew that i am, I want to know about what kind of websites you use to book your hotels? I've been using Priceline thus far but last weekend I went to a hotel but when i arrived, they said they were all booked, even when priceline gave me a fucking confirmation. now it's back and forth with the customer service and frankly i dont have time for this kind of shit.

so let's make this the unofficial wso thread on best hotel booking sites to use :D
