Sometimes it's OK to fall asleep in class. That's the case at this hotel in Portland, Ore., which was fashioned out of an unused elementary school that saw its first students nearly 100 years ago. Some of the hotel's 57 rooms are located in actual classrooms, with blackboards, desks and other educational paraphernalia still intact. The property now has a movie theater, several small bars with different themes, a soaking pool, and an onsite brewery. Murals and other works of art are a nod to the hotel's educational roots.
