How about a weekend retreat to the Bahamas or a Cruise??
You would be (and I *definitely* would be) there, but our experience tells us that not many more would be.
I always find our confernces to be great evidence of a big difference in gender roles. So many men can travel to 4 and 5 day conventions in exotic locales without any/much problem. But we've found with our conferences that even one night away is often hard to swing for mom. Heck -- never mind three days in Bermuda -- a lot of our attendees skip out on the very end of the days so they can be home for dinner and homework/bedtimes.
