No idea, my father in law is a member so I've played there often, but he always picks up the tab. I vaguely recall playing there 10 years or so ago and having a round of drinks afterwards and him getting change from a tenner. Might be wrong but I suspect it is still, as Chris suggests, dirt cheap.
Mark,
Did your wedding ceremony include any activities at the club...It is a common custom in the US.
John,
Until recently dogs had more rights at Muirfield than women (in the early '90s my wife (a good mid-teens handicapper) and I played with her father on a cold, bleak April day. The Ladies changing rooms consisted of a Portakabin by the side of the clubhouse. Having cahnged after our round, she came round to the front of the clubhouse to join us, where she was refused entry until "collected" by a member. She had to stand in the rain until her father had finished showering before being allowed in. Things are, I gather, better today but I suspect that women featured even below Americans on Paddy Hanmer's league table of human beings. Since that day Lorna has refused to return to Muirfield until women have equal rights in the club. She is not expecting to return any time soon.
I also suspect that the last thing the members of the Honorable Company would want at their club was a wedding party.
All of which is a long winded way of saying that no, no part of our wedding day involved Muirfield (in fact we got married at my college in Oxford, so geographically it would have been difficult as well.
I don't know of any UK tradition or custom of wedding ceremonies or part of them taking place at golf clubs, though I have been to a wedding reception at Moor Park Golf Club, which I guess is more of an American style country club, recently. I suspect that this is another of the differences between the established exclusive UK courses and their equivalents in the US, as addressed in the other Muirfield thread.
