The GW is the sister location to the Milleridge. I checked out the GW - and would have had my reception there if the date was available. (now i'm at the Milleridge and very pleased - GW was closer to the Church).
Are you having it in the room with the fireplace or the 2nd floor window room (both are very pretty). I think the facility is great and since its run by the same folks at M, you should have a great time! (read some of the postings by the Milleridge brides)
