I think a drop-in childcare would get a lot more use than the system they have now. I certainly never felt comfortable about the idea of calling up a random person with little or no background information and asking them to come to my hotel room, which may have been a 15-20 minute walk from the conference center and ask them to watch my then-infant son.

Maybe it's a discussion we should get started on the AASWomen list - what kind of childcare do people *want* at the AAS meetings?
