Call them
Anytime I believe, I know if you make a reservation they will leave you a folder with a map, Wi-Fi password and cable channel list out waiting for you after hours. If you don't have a reservation you can still just show up and look at the list available and hook up and take care of it when the office opens. I know they are open until 7:30pm sooner on Sunday not sure of open time I believe 8 or 9
Anytime but usually after 12 inorder for people to vacate the site
