If you decide to spend your vacation at a 4-star hotel in Mongla, you'll typically find plenty of conveniences to keep you relaxed, such as a restaurant, gym and pool. You can enjoy excellent service and upscale accommodations. Opt for a 5-star hotel and you'll have access to a few more bells and whistles — think on-site spas, concierge assistance and indulgent turndown services. You're likely to get additional amenities and first-class services at a 5-star retreat, but both are great options for luxury guests.
