Cheap sleeps on the Maine coast? Amid the luxury hotels, fancy inns, and white-bread chains there are reasonably placed accommodations that include no- frills motels, bed-and-breakfasts, and intriguing options such as a former monastery and a lodge built by Civil War veterans. These possibilities, listed from south to north, are convenient to coastal locations; a few are waterfront. Each has peak-season rooms for less than $100 per night. Travel spring or fall and reap even better rewards.
