I guess I'm convinced the F3 ceremony was at Cap Maison, as was Jake's bench scene.
The ABC press release suggests/hints that the F3 ceremony took place at Cap Maison (right?) and the Cap Maison FB page has this: "another date for the diary - February 14th we will feature on The Bachelor on ABC! The Rose Ceremony was filmed at Cap Maison." (not quite the right date!)
Moreover, I think the bench probably came from Cap Maison.
The parts circled below might match up too - again Cap Maison (so much for my Windjammer theory!!!!!)
