My work held a conference here. The grounds were beautiful - it was a very relaxing area.
I stayed in the Silo building. At the time, there was a stink bug infestation and despite the best efforts of the staff, I ended up killing about a dozen of them before going to bed (I didn't feel like bothering housekeeping when I had a nice magazine that worked just fine). The bedroom was large and overlooked the pool, while the bathroom was nicely redone. The free WiFi worked great as well. I liked that the building wasn't a typical 'high-rise' hotel with a huge parking lot. There were bicycles available to bike between the Silo building and the main building, although it was not a far walk. The walls weren't extremely thin, but I could still hear some people enjoying watching a football game in another room.
I cut through the English garden at one point and was dismayed that it was full of spider webs and overgrown greenery. It's beautiful to look at, but it seems as though it wasn't very well kept up.
The room we held our conference in had some temperature difficulties - the cold air blew right on me in one corner of the room, but the room was a bit warm on the other side.
The food was good - a decent variety of foods that were all organic and some made from the manor's own garden. I especially liked the honey butter - I could have eaten that for a meal itself.
From what I overheard, the conference was a bit expensive (and they charged something like $100 to add a guest speaker for dinner), but I think the quality was very good.
I enjoyed having our work conference here and think if you're looking for a beautiful spot for a wedding, this should be a place to check out.
