If I may make a suggestion to you. It may be a good idea to actually get a rental car from the airport. My reasoning is that you will want to go to Q-Masters during the off time of the tournament. Q-masters is about 4.5 miles away from the Convention Center and cabs aren't too cheap in the Norfolk area so it may be cheaper just to get the rental.
I was at Q-masters last month and I could have sworn I had someone tell me that they actually run a shuttle 24hrs a day from the convention center to Q-Masters, but I am not sure on that or if the shuttle was just for the players in the tournament.
Hope someone on AZB could clarify the shuttle for you and me, it may save you some cash on a rental car.
Have Fun.
