If you decide to vacation at a 4-star hotel in Sidney, you'll usually find lots of amenities to make sure you're relaxed, such as a gym, restaurant and pool. You can experience excellent service and upscale surroundings. Go for a 5-star hotel and you'll get a few more bells and whistles — think on-site spas, concierge assistance and opulent turndown services. You're likely to get additional amenities and premium services at a 5-star stay, though both are awesome options for luxury guests.
