Further to my original remarks about the network at PyCon, this has probably been the biggest complaint I've heard people make, and the post-mortem continues as wireless associations continue to fade in and out during the sprints. Considering that
a) The networking company is at least part-owned by Marriott, and
b) A five-figure sum was negotiated for the wireless coverage and Internet connectivity
the results were very disappointing. For the record STSN didn't have anyone on-site, and there was no evidence that they had sent anyone over beforehand to do any testing and verify that the network coverage would be robust when descended upon by a crowd of geeks, most of whom were expecting the same kind of coverage we got at GWU.
I've no wish to prejudice any negotiations here, so I'll content myself with saying that during the sprint startups, when we shared a room with the organizers' debriefing, I was reminded how difficult it is to get everything right when you depend on third parties for so much of it. This issue isn't over yet, and meetings will follow to pick over the carcass.
