If you decide to book a stay at a 4-star hotel in Hulu, you'll usually find plenty of amenities to make sure you're relaxed, such as a pool, restaurant and gym. You can look forward to excellent service and upmarket surroundings. Pick a 5-star hotel and you'll get a few extra perks — think concierge assistance, on-site spas and nightly turndown services. You're likely to get more amenities and first-class services at a 5-star retreat, but both are terrific options for luxury travellers.
