A highly statistically suspect sampling technique, but one that
may be valuable... ask your docents who are greeters, etc., to
ask some folks, "What's the most interesting thing you've learned/seen
today?"  While it's not quantitative, consistent mentions of some
exhibit or program merit a closer look.
