My husband is Director of Christian Education at a Presbyterian church.  He
calls them "lock-ins" rather than sleep-ins, for reasons others have given
here.  Anyhow, youth ministers and DCEs are great resources for
get-acquainted games and group-building activities that could be tailored
for museum use, as well as practical advice about unruliness, kids-to-adults
ratios, elderly bodies on hard floors, meals and snacks, whatever you need
to know.  If you need any book titles for reading about the above subjects,
let me know and I'll get you a bibliography; if you'd like to talk to Robert
I can send you his phone #.
