The basic idea behind Hotels.com is that it's a simple place to book hotel reservations, often at a discount. You give up perks like earning loyalty points or statuswith your favorite hotel chain, in exchange for the convenience and price. I guess, technically, Hotels.com has arewards programthat it shares with its parent company, Expedia, but it's pretty bad. 

Perhaps the thought is that people who are using Hotels.com to search primarily for the lowest rate will be willing to give up on things like earning rewards. Unfortunately, it also seems like the company thinks people are willing to also give up other things--like a great experience.
