I was in a congress with +1500 people and we liked it. It is a spacious site, with different rooms and quite well organized.
I imagine that the cattering are external companies, but when I was there we did not like the food at all.
As for the rooms and the site is quite good: spacious, organization, cleanliness, signage.
The WiFi is quite bad, it does not support large influxes of people, I would recommend that they implement a professional solution for this type of environment.
