I just joined 關鍵 in Easter. I'm so satisfied with those tour guides. They are professional and make you feel respected and safe in Thailand. I stay in Pattaya for 3 nights and 1 night in Bangkok. The hotel in Pattaya was really fantastic. stay on the high floor, seaview and with balcony. The price was only $1,399 . Compare with other travel agent at least save $1,000 per head. But I think most important is: Are u lucky enough to meet a professional and nice guide??
Sorry, i 've misunderstood. I think you are looking for the tour. For package, I think not a big different with the travel agent. Last October, I went to Bangkok by myself. I just bought the air-ticket (TG) in新華 and booked the Hotel by my friend in Thailand. It only cost me around $100 (500 B) at that time per night.
