If you choose to stay at a 4-star hotel in New Hampshire, you'll typically find plenty of amenities to make sure you're comfortable, such as a restaurant, pool and gym. You can enjoy excellent service and deluxe accommodations. Opt for 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're likely to get more amenities and first-class services at a 5-star retreat, but both are terrific options for luxury travelers.
