Part of great travel is doing things differently than you do at home. So next time try leaving the chain hotel behind and check into something kind of odd.  Travel & Leisure has a roundup of the World’s Most Unusual Hotels. Most are outside the U.S., but Boston’s Liberty Hotel, Louisville’s 21c Museum Hotel, and Earthship Biotecture, with locations in some western U.S. states, made the cut.
