If you choose to vacation at a 4-star hotel in Vaal Marina, you'll usually find plenty of amenities to keep you relaxed, such as a pool, restaurant and gym. You can enjoy top-quality service and deluxe accommodations. Opt for a 5-star hotel and you'll get a few more perks — think on-site spas, 24-hour front desk and opulent turndown services. You're likely to get more amenities and exclusive services at a 5-star retreat, but both are great options for luxury travelers.
