I've seen this hotel sell out (or nearly so) many times before. They have some rather large meeting spaces -- It's a great place for a corporate 'retreat' or highly specialized conventions where you need to globally fly in lots of corporate bigwigs. Not unusual if you go to the lobby at 8PM and run into a large crowd of people dressed in well-pressed suits (and other corporate wear) getting sloshed on martinis.

This type of event is back.
