What's the difference between 5-star and 4-star hotels in Grassy Key?
If you decide to book a stay at a 4-star hotel in Grassy Key, you'll typically find lots of conveniences to keep you comfortable, such as a restaurant, gym and pool. You can look forward to top-quality service and upscale surroundings. Choose a 5-star hotel and you'll get a few more bells and whistles — think on-site spas, 24-hour front desk and nightly turndown services. You'll most likely get additional amenities and premium services at a 5-star retreat, though both are terrific options for luxury guests.
