The 14-day Glory of Bangladesh was a wonderful tour. It had a varied and excellent itinerary of the big-city sights of Dhaka, the wildlife of the Sundarbans (lots of birds, boars and deer), interesting archaeological sites and UNESCO World Heritage Sites, and villages that were very interesting, very non-touristy, and welcoming.
The people of Bangladesh were very friendly and open. We had great fun taking photos of all. Our tour guide spoke excellent English and was very helpful and informative. The only negative was the government limiting my visa because of the upcoming election. But the closed and very quiet Dhaka was perfectly safe and we wandered around freely.
I would strongly recommend both visiting Bangladesh and Bangladesh Unbound.
