Though it is a little touristy. I really enjoyed taking a tour of the klongs (rivers) in Bankok. You catch a boat that holds about 10-15 people and has a V-8 engine mounted on the back of it with a long (10-20 ft) propellor shaft that the operator dips into the water when wants to go. Takes you along some of the outskirts of Bankok and you can get food, trinkets, snakes show, etc. along it. Is a lot of fun. At least they did this 15 years ago when I was there. Assume they still do it. Visit some of the temples too. I believe they have the worlds largest Buddah there (someone correct me if I am mixing this up with another city). Any way enjoy you trip.
