[Prudence]

I could really see doing this with kids. They appear to have some built-in times with separate kid/adult activities. I would also consider it for my first trip somewhere. My ideal first-time trip to another country involves some time in tour and some time on my own. I kind of like to stay in the safety of the herd until I feel I have a grasp on how not to inadvertently irritate the locals with my wacky and offensive American manerisms. Plus, I like to hit sort of the "top ten" touristy things AND do the wandering the street thing. Second time around, then I feel comfortable going it alone. Compared to other tour packages, these seem more expensive, but also potentially "nicer".
