If you decide to spend your holiday at a 4-star hotel in Blue Mountain, you'll typically find loads of amenities to ensure you're relaxed, such as a gym, restaurant and pool. You can experience excellent service and upscale accommodation. Choose a 5-star hotel and you'll have access to a few more bells and whistles — think concierge assistance, on-site spas and indulgent turndown services. You're likely to get additional amenities and premium services at a 5-star getaway, but both are terrific options for luxury guests.
