the cisco folks used about 24 access points(overkill) for the ietf in sandiego that was enough to blanket the conference center and the hotel below the 3rd floor...
One thing which I would find useful is connectivity which extends into the hotel rooms themselves. Wireless would be nice, but most hotels don't cope with this very well. One conference I went to (I can't remember if it was NANOG or USENIX) provided dial-in on a hotel extension, which was useful!
