Yeah, I've been to a couple conventions in that hotel as well. It's one of my least-favorite Marriotts anywhere to be honest.

I can understand the complaint about how a large convention takes over a hotel and deprives non-convention guests of services (e.g., a large number of simultaneous private parties at various pools, bars, restaurants, etc.), but that's a bit different from the typical resort vs. non-resort issue with Marriott.
