On the plus side, hotels.com has a rather nice phone-optimized site for finding and booking hotels. On the minus side, the "booking" part doesn't actually work. When I tried booking a hotel in Portland, after giving it all my payment and contact information, it just redirected me back to the main page. No error message or anything else. If I tried accessing a page in my browser history, it would similarly poot me back on the main page. Not useful!
