If you decide to book a stay at a 4-star hotel in Frederick, you'll typically find lots of conveniences to keep you comfortable, such as a pool, restaurant and gym. You can look forward to excellent service and deluxe accommodation. Choose a 5-star hotel and you'll get a few extra bells and whistles — think concierge assistance, on-site spas and opulent turndown services. You're likely to get extra amenities and first-rate services at a 5-star stay, though both are awesome options for luxury guests.
