The 228-room landmark Royal Marine Hotel was built to impress, and impress it does. Extensive renovations have balanced traditional Victorian refinement -- much of the original plaster work and stained glass remains -- with modern facilities. The location is not great for exploring Dublin, but the seaside suburb setting is a destination in itself, and the DART train to central Dublin is within walking distance. Rooms are pleasant if not remarkable but include some nice luxury touches, and many have sea views. Travelers would be hard-pressed to find a four-star to challenge this hotel's history and class.
