If you're there for an extended time, purchase a weekly parking pass for $30.
They let us check in a bit early. We were there because our son was at Children's Hospital, and we used the hospital parking deck. The hospital took care of parking, and the hotel is so close, the walk was no problem.
Check in time is 3:00 but they'll let you check in at 2:00. You also have to pay for parking.
Seems to me it was 3:00 PM CST. . .
