Convention center, a little more pricey we $25 but if you park in lot c than your walking a mile. If you go the convention center parking lot website you may be able to purchase them in advance for cheaper. Hope that helps. Plus in my experience it is safer for me and my kids who take longer to get in and out...
I have noticed the garage parking was available as well as outdoor parking lots that ranges in between $6 to $25. Outside parking, across the street may be your cheapest and best option.
