I got married almost two years ago at McMenamins Cornelius Pass Roadhouse. You don't have to pay for the area you just have to buy at least $5000 worth of food and alcohol which I was going to do anyways. There are many different settings I had my ceremony in a grassy area and my reception at the octagonal barn. Turned out great and i don't regret it at all.
We were married at Grandma's Garden Nursery. It is owned by a friend of ours, and had 120 guests with no problem. Here is her website, I would call and talk to her. Had a wedding in the grass, and a reception in the barn and under the huge tree outside.
