If you choose to spend your holiday at a 4-star hotel in New Castle, you'll usually find lots of conveniences to ensure you're relaxed, such as a restaurant, pool and gym. You can experience high-quality service and upmarket accommodation. Choose a 5-star hotel and you'll have access to a few extra perks — think on-site spas, around-the-clock concierge and opulent turndown services. You'll most likely get more amenities and exclusive services at a 5-star retreat, though both are awesome options for luxury travellers.
