At 5 days for $8, it adds up quickly to $40 just for parking your car.
If you wanna park for free, you can park across Kirkman Road at the TGIFridays, which is next to the Holiday Inn and walk. Be careful crossing Kirkman, because it's like 10 lanes of fast moving traffic. After you cross, walk to the parking garage, go inside, walk to the elevators, go up to the 3rd floor, and take the moving sidewalks.
