If you choose to vacation at a 4-star hotel in Kasa-ri, you'll usually find loads of conveniences to keep you comfortable, such as a pool, gym and restaurant. You can look forward to excellent service and upmarket surroundings. Go for a 5-star hotel and you'll have access to a few extra bells and whistles — think on-site spas, 24-hour front desk and indulgent turndown services. You're likely to get more amenities and premium services at a 5-star retreat, but both are superb options for luxury travelers.
