Having seen the room block notification, I went online to try and book a room at the Hilton. I understand that rooms are in high demand, but the situation is really odd... their web site is showing that Tuesday through Friday are sold out, but not the weekend (which is the weird part). I called them and they had no idea what was up, and could only confirm that the rooms are indeed sold out through the week.
It would be incredibly weird if Bronycon attendees booked up the weekdays, but didn't take the weekends as well. I looked to see if there was perhaps another convention during that time, but couldn't find anything. There's an "APCO communications" convention the week after, but I couldn't find anything for the week before. Any ideas on what might be up? (And to clarify, it's not the "discount rate" block that's sold out, it's all rooms period, even full price.)
