I flew United Airlines there a few weeks ago and it was a great experience. The waiting area at my gate had couches and bar height tables with plug ins for devices. TVs too. Security line was long, but it was always moving. There are lots of shops and restaurants of every kind there.
I use Rightway for all our OSHA consulting. They are extremely thorough and informative. John is an excellent trainer and goes at the right pace for the staff. He helped set up all our SDS manuals and OSHA guidelines. And he is always available for any questions. Definitely recommend!
The convention center is bright, spacious, and clean. The room numbering is a bit bizarre which makes navigation somewhat more challenging but the signage is good and there are multiple information kiosks.
