49th-IETF conf room planning

[Lane Patterson]

This has likely been proposed previously, but I would like to
raise the topic of mapping adequate conf rooms to WGs and BOFs.
I have now attended 3 WGs that had to turn away attendees due
to extreme lack of space, and several others that had plenty of 
extra unutilized space.  

Would the IETF organizers consider requesting WG/BOF attendance 
plans upon registration?  Are there other suggestions for 
improvement in this process?

Respectfully,
-Lane
