Elie is a fabulous place and a very unusual club. During the Scottish school holidays the town/village is full, mostly with families who return every year. A large proportion are members of the golf clubs (three clubs use the course, The Golf House Club, Elie & Earlsferry Ladies (these two are closely linked and share a clubhouse) and Earlsferry Thistle). This means that an unusually high proportion of member play takes place during that period. There are also a number of competitions during that time, many during the week, and most fully subscribed. That means, during that time, a lot of demand for times from members. For several years the club has operated a ballot for members for casual (i.e. not in competition) tee times. If you are flexible, you'll normally get a time but if you are more restricted as to when you can play, it's a problem. For a while, during that peak season, visitor play has only been possible during one hour in the afternoon. The rest of the year the club is MUCH quieter and visitors are very welcome.
This change isn't really a big one. Visitors will still be very welcome at times when there is capacity. Hopefully everyone would agree that it's reasonable for a club to limit visitor play when it might prevent members getting a game. I don't think this is any significant change of policy.
