Thank u everyone. And I found out the times up to 9pm
Im not sure of the exact time, check in is at 4. If they are in the booth they will take your Id to check. Then have you register in the morning. There is not always someone in the booth, so I just drive in & register in am as well. Sometimes I get off work kinda late & we make sure were not to be loud when we park.
There is someone at the booth 247. I'm not sure exactly what the latest time you can check in is but you just might irritate your neighbors if you do it the mill the night
