If you choose to stay at a 4-star hotel in Sunji-ri, you'll usually find plenty of conveniences to keep you comfortable, such as a pool, restaurant and gym. You can experience high-quality service and upscale accommodations. Pick a 5-star hotel and you'll have access to a few more bells and whistles — think concierge assistance, on-site spas and nightly turndown services. You're likely to get more amenities and first-class services at a 5-star retreat, but both are awesome options for luxury guests.
