Earth to MoC...Come in MoC!

I am speaking over the next two days at a conference that my firm is sponsoring. For the past two years, this conference has been held in a hotel downtown. I was prepared to go straight there tomorrow morning. Two minutes ago, I overheard a conversation in my office where someone mentioned something about a hotel across the street from our office.

It turns out that the conference is at the Roosevelt Hotel which is literally across the street. When did that happen?
