If you decide to book a stay at a 4-star hotel in Scotland, you'll usually find lots of amenities to ensure you're relaxed, such as a gym, pool and restaurant. You can look forward to top-quality service and upmarket accommodations. Pick a 5-star hotel and you'll have access to a few more bells and whistles — think around-the-clock concierge, on-site spas and nightly turndown services. You're likely to get additional amenities and first-class services at a 5-star retreat, though both are fabulous options for luxury guests.
