Check their photography policies.
I just read a warning on my local board about a girl who got kicked out of her hotel room during a B-session b/c it turns out that hotel didn't allow photography UNLESS you are getting married there. I decided to contact the Holiday Inn manager (where our hotel block is at) to see if they had the same policies, and they do.
So it looks like I will be searching for another place to get ready. The church doesn't open until 3pm - meaning, the air will not be at its set temperature until 3pm, so I will not be setting foot in that building until 3 lol.
Crap.
