If you decide to spend your vacation at a 4-star hotel in Saint Croix, you'll typically find loads of conveniences to make sure you're comfortable, such as a restaurant, gym and pool. You can enjoy top-quality service and upmarket surroundings. Pick a 5-star hotel and you'll have access to a few extra perks — think concierge assistance, on-site spas and opulent turndown services. You're likely to get more amenities and first-class services at a 5-star retreat, though both are great options for luxury travelers.
