Minor Arisia problem

It's been striking me in the past week just how many people I _didn't_ see, or didn't see in more than just passing (and that passing only once), at Arisia.

Some of this is due to some social choices I made, I know. Some is certainly due to those people's similar choices, and some, I suspect, is due to the layout of the hotel.

Hm.
I wonder if there's anything that can be done about that 3rd factor.
