I've been with several companies that have used the Santa Convention Center for large company events and find it to be a really good experience overall. They know how to cater to huge outings with thousands of people, which is no easy feat. The main rooms are massive, seating is as comfortable as it can be with the type of chair required to hold that many people and sound/acoustics/visuals for all the presenters/stage participants is excellent.

The only negative is the number of bathrooms for such large crowds. But I've stayed in the adjoining Hyatt Regency hotel each time, so didn't have much of an issue.
