i hate to say this....we have been on quite a few tours with ETBD....this one wasn't great....sadly, our group turned out to be made up mainly of people who wanted to chatter - ALL THE TIME - on the bus, during walking tours - very disrespectful - to the guides and to the few of us who were trying to pay attention....i do not know if there is a good way to do this - but - perhaps - the back of the bus
