However, unlike dining, you can't make it online. You must call, and the phone line doesn't open until 7 AM.
I remember, because I was on the phone in the hospital exactly at 7 AM on my 180th day out. (My husband was having blood drawn). We were staying offsite, and I wanted to make sure I got DGD in on her birthday. DGD's birthday is a very popular day for dress-up. October 31. I did get my time though.
