Well... I correct myself... I don't love tours.
BUT... I wanted to get to the Mekong Delta before leaving Vietnam (less than two months!) and the easiest way was through SinhTourist... $20 for the day, including lunch, including transportation, and including a TON of different activities and things to see!
Anyway, this tour turned out alright. There were probably about 30 of us on the trip.
(Nice handrails in the photo above, huh!? ...They began about halfway down the cement dock.)
