Okay. By the way, if it IS the same guy, he already has a room reserved. If you decide to share, you can put your heads together and decide what the best plan is (i.e. whether to cancel a room).
And now that I think about it, if it isn't the same person, I'm sure he'd still greatly appreciate it if you wanted to share a room, since he's on staff... I'll let you know when he responds (unless he posts here).
