If you choose to vacation at a 4-star hotel in Plymouth, you'll typically find plenty of amenities to keep you relaxed, such as a gym, restaurant and pool. You can enjoy top-quality service and upscale surroundings. Pick a 5-star hotel and you'll get a few more bells and whistles — think around-the-clock concierge, on-site spas and indulgent turndown services. You're likely to get more amenities and exclusive services at a 5-star getaway, though both are superb options for luxury travelers.
