I seem to recall the Canadian Museum of Nature in Ottawa doing "sleep-overs"
for children's groups.  You may want to contact someone there.  I know I have
seen tv news reports about this and always thought it was a great way to
publicize the museum in addition to its being a great program.  If you want a
contact name contact me off list and I will try to find someone there you can
get in touch with.

They are also well known for their ghosts!!!!!!
