If you choose to spend your vacation at a 4-star hotel in Radisson, you'll usually find loads of amenities to keep you relaxed, such as a gym, restaurant and pool. You can enjoy excellent service and upmarket surroundings. Choose a 5-star hotel and you'll get a few more bells and whistles — think on-site spas, around-the-clock concierge and indulgent turndown services. You'll most likely get more amenities and first-rate services at a 5-star stay, though both are terrific options for luxury guests.
