The Marriott hotel room thermostat went down to 40° F. This is a blessing for those of us with unusual illnesses that require a constant supply of cool air.
The instructions that Readercon gave to panel leaders included the admonition to defenestrate anyone who let his cell phone ring audibly. I shouldn't have gotten my hopes up. Several phones went off in the middle of panel discussions, and to my extreme disappointment, no one was actually defenestrated.
The sound arrangements for the panels were suboptimal. The speakers were set in the back, or on the side, with weird effect of seeing a panelist's mouth move, while their words came from behind you. Disorienting.
I should learn to hang out in the hotel bar. I think I'd meet more people. I bar badly, though.
