Do you have a room/area where you host a wedding ceremony and a reception for @ 160 people?
They have several large ball/party rooms.
Check with the hotel
We did look into wedding options there a few years ago. We were looking to accommodate 100 ppl and they had no problem. That whole area books up quickly though, so if your thinking this year you may be disappointed. Excellent place to stay though and continuously expanding and improving.
They have fantastic rooms, I'm unsure about the number of guests that can be accommodated . Just call their number on the web page and ask for Ann Saunders or Grace McQuarrie. Amazing and helpful
