TLDR; we would recommend this venue, but overall had a couple issues with staff.
Our initial point of contact, Jessica, was, frankly, fantastic. She was extremely helpful during e...ach stage of our planning process, and was very thorough with explaining all of the fees, what we were responsible for regarding set-up, and what all the deadlines were regarding payments and vendor information. The process leading up to the wedding was very easy, and we enjoyed having Jessica as our guide through the process.
The day of the wedding, however, was not as easy. We did not get the names of the staff that worked the day of our wedding, but the two women who were there were great and very friendly. One of the men was not as friendly; not only did he loom around the venue with his hands behind his back, not speaking to anyone who greeted him, but when asked about the electrical outlet outside, he had no idea where it was, and did not ask another staff member where to find it. The father of the groom was outside for 20 minutes in the sweltering heat trying to find the outlet (which he did eventually). Additionally, while the bridal party was being introduced into the reception (we were in the Foyer, walking into the Living Room/Dining Room), he walked through the front door and stood there while we were being introduced, making it difficult for us to get photographs without him in it. We were under the impression that all staff would be available if needed, but out of the way and not seen during the event.
Additionally, this was a private event. There were several groups of individuals NOT in the wedding party, nor a part of the support staff, that came through the front door of the building while set-up was occurring, with no Mansion staff in the Foyer to tell them to leave. At one point, these individuals were roaming around the gallery upstairs, attempting to get into the rooms where members of the bridal party were actively changing. One of the groomsmen had to tell these individuals to leave.
Overall, we loved the architecture of the venue, it truly is beautiful, and enjoyed working with Jessica, but there were some definite issues with public presence during the set-up, and incompetence/rudeness of one of the staff members. If you’re looking for a beautiful venue to host your wedding, this is certainly it, but be advised that some of the staff are not very helpful, and you are probably on your own with dealing with the public trying to view the gallery.
