Orchards is owned by MHC but leased out to Arnold Palmer Management for the operational side of things. Golf course is adjacent to campus; students play for (virtually) free, faculty get a discount, they also have a private membership program.
Taconic is, I believe, owned and operated by Williams College, with the golf course next door if not directly adjoining the campus (depends on where the property lines are, but it's very close). Students get a major discount, as do faculty and alumni. Last I heard, it was not open to the public for daily-fee play.
