We are a family of four (two young kids) and booked Chansay for two days to tour Vientiane and Vang Vieng. He did a very good job and we had a blast. He was great with the kids and tailored the tour to our tastes. Only opportunity for improvement is with the language - his accent was sometimes hard to understand, but it didn't hinder our enjoyment. You can see our blog post on the trip here: http://www.farleyfamily.net/2014/05/22/vientiane-vang-vieng-laos-vacation/
