We'll be in BK in February and would like to go on a day tour to visit the Bridge over the River Kwai combined with a train ride and a boat ride on the River. We don't want to go to the Tiger temple or the elephant ride. We would like to do this tour in a small mini-bus with small numbers of people rather than a large coach. The only company I can find to do this trip is City Discovery tours but it is in a full size coach. Does anyone know a company I can do this with a small group please ?
