Where do you see that it says it is being held in the convention centre? I can’t find this info?The convention center has 240,000 sq. feet of meeting space. I'm betting there will be at least 2000 seats.
Parking seems to be $30. Ubers might be the ticket if you are staying elsewhere.
Dining at the hotel is limited -- a steak house, a breakfast place and a couple of bars -- but there are a bunch of restaurants about a mile south -- Vietnamese, Irish, Brazilian, pizza. And an outlet mall that has some restaurants and a food court.
