Any clubs I am associated with - including the great value overseas membership at Carne mentioned in the article - have an unlimited number of guests that can be taken on by a member.
I do enjoy these topics about overseas memberships.
I joined Carne 2 years ago, when it looked like they were in some trouble. My first trip as a "member" is planned for June. While there is no restriction on number of guest total it was pretty surprising that I was only able to sign in 2 guests/day and not 3.
Not quite a membership but this year I also got on the links ticket waiting list. A bit over 1400 on the waiting list and only 100 new folks received a ticket last year...so in 14 years I should be good to go. Before then I hope to join one of the local clubs and get the comp ticket (no idea how I'll figure which one to join).
The thing with these two options is I didn't need to know a member and the value is incredible compared to almost anywhere else in the US.
I also envision I'll join somewhere in the south of England before I die.
