A new online hotel room-sharing program is either a why-didn't-somebody-think-of-this-sooner brainstorm, or completely nuts. Easynest, which launched in May, capitalizes on the fact that most hotel rates are based on double occupancy, whether or not there are two occupants. By finding someone to share the room - and the cost - rates are cut in half. It works like this: You create a profile with Easynest, list the locales you're headed for (or interested in going to) with your dates, and wait for a "host" (the hotel room booker) to contact you. Host and "guest" then agree on dates, costs and other particulars, and the guest pays the host directly. For now, the service is free, though the site's founders say they'll eventually charge a commission for the service. Current membership is about 400. Get the full story at USA Today
