3pm
Check-in begins at 3PM CST. To inquire about the availability for early check-in, please call the hotel on the day you are scheduled to arrive. If you will be arriving later that 12am, please call the hotel so that we may keep your room ready for you.
"3 pm." By which they mean any time between 3 pm and midnight, depending on how they feel.
I think it was 15:00 check in. Earlier times can be arranged by contacting them though.
