Lotto gave me 5:21 EST.
Probably just past the cutoff for downtown. Last year they were gone at 2:11 p.m.
Here's the response from several hundred people on Facebook if you're interested.

5:44 for me.
4:22 eastern, I feel all downtown hotels will be gone by 2. Aw well I've been lucky in the past and maybe I'll get lucky with a return later this year. I've got a few favorites a few miles away hopefully I can get one of those.
I got 8.07pm Eastern which is 1am in the morning for me. My last GenCon for a fair few years was hoping for one that got me near Downtown oh well.
There is a live thread. Most downtown hotels are sold out.
