I guess if you were having a Wishes event with 20-34 people and didn't mind paying a $3,000 venue fee to use it they'd let you do it. But they would probably discourage you from also holding your reception there, since it would need to be set up during the ceremony. Unless you held a pre-reception somewhere else and then went back....
They're inflexible on the locations for Escape and Memories events, though.
