My wife and I basically found it to be a shake-down. They greeted us with a song and a dance, which takes about five minutes, and is cool. Then we did the vertical jumping thing with them, which also lasts about five minutes, and that's also fun. Then we spent about five minutes in one of the huts, and that's where the tour ends and the hard-selling began.
This was supposed to be the half-way point of the tour. At this point our guide requested his tip. I had a nice one planned for him at the end of the tour, but I was turned off by the demand, so I gave him less than I had planned. He then showed us their crafts, but wouldn't tell us the price. The chief said, "pick what you want, and we'll discuss the price afterwards."
We picked three things - trinkets that respectable souvenir shops on Zanzibar would have charged $25 for total. The chief asked for $125, laying on the guilt trip pretty thick about how we should help support the tribe (which we were doing just by paying to visit, I was led to believe).
We only bought one of the things, and the enthusiasm basically went out of the tour. They took us to see the kids' school, where the children physically tried to snatch our belongings off of us, and the adults did nothing to stop this.
I sort of expected as much, but my wife was highly disappointed.Edited: 12 September 2013, 22:53
