I agree with Mike that the essence of a members club is 'shared interest'. Introducing an abundant variety of different membership categories, is not in line with that principle.
Unfortunately, many members clubs, also in my country (The Netherlands), are faced with rapidly declining memberships. A lot of these clubs have shut their eyes for this development in the past years, or are in a state of denial still. In many cases the clubs are run by older gentlemen, who used to be successful in business, but have lost their management skills, sense for entrepreneurship and marketing as soon as they became in charge of club policies. And sadly, complacency is an attitude that proves to be extremely persistent amongst these board members.
When things become really troublesome, a common reaction is to make membership more attractive by lowering fees and by introducing lifestyle concepts. Pricing can be an effective marketing tool, but in this case it isn't. If traditional members clubs want to survive, they have to start with changing the other 'P's' in the marketing mix. Most importantly with the 'P' of Product.
I'm convinced that there is still a market for private members clubs, where members indeed share interests and values and where golf can be played in a pleasant, relaxed atmosphere. But that isn't necessarily about wearing jackets and ties, playing the same tournaments over and over again and organizing bridge drives. There are, at least in my view, other, more contemporary ways to bind group of (young) people together within the confines of a private golf club.
