I like ACNW's 'gaming suites' ... That way they plan game locations in advance. Why don't you do this?
UPDATED 3/12/09:
The committee is actually looking into this option. Because of the system used by Embassy Suites in assigning rooms, we don't get the room numbers in advance, which makes many things difficult, scheduling-wise. Also, at ACNW, the rooms are very different sizes, with only some of the room appropriate to hosting games; thus it is important for them to single out certain rooms to shoulder the burden of hosting all the games.
It is possible we will do something similar for 2010, if it works out in some way.
