Not so much an inn as a luxury retreat, Cape Elizabeth’s best hotel has made the successful transition from relaxed seaside getaway to destination resort. Yet they’ve done it while retaining a wonderful sense of place: suites and dining areas emphasize Maine-themed art and foods, while summery gardens and ocean views tantalize through the windows. An expansive, lovely spa was added in 2008, as were a walk-in cave, fireplace rooms, and bi-level spa suites with double Jacuzzis. A further set of cottages (townhouselike suites) in an outbuilding add full kitchens and extra bedroom or bathroom space. Especially welcome is this inn’s move toward green practices: It’s the first hotel in Maine to burn biofuels, operate carbon neutrally, and employ printed-paper key cards. Recycled materials and low-flow toiletry also predominate. Need still more green? A walkway leads to one of Maine’s best beaches.
