The tour guide ask money more then the trip cost with no receipt. Drop customers in new place without explain the locations to customers. Didn't spend time to do his job as tour guide, when you get on bus late then he said which he just drive away the bus and come and pick you up after few hours. Ask tips more then one hundred dollars for 4 days, we didn't pay him that much that make him made and harassing us all the way back home for 6 hours. Very scary people for this travel agency they located in China Town Boston, never go there again they ripped you off and try to scare you. I am still receiving the phone call for asking the tips that they think they should get, ridiculous...
