If you choose to book a stay at a 4-star hotel in St. Mary's, you'll usually find plenty of amenities to keep you relaxed, such as a restaurant, pool and gym. You can look forward to top-quality service and upmarket accommodations. Opt for a 5-star hotel and you'll get a few extra perks — think on-site spas, 24-hour front desk and opulent turndown services. You're likely to get additional amenities and first-rate services at a 5-star retreat, though both are terrific options for luxury travelers.
