Taking an outstation Royal Club is actually a good idea.
Other clubs affiliate KGNS are
Kelab Darul Aman
Bukit Jambul
Seremban International
Ayer Keroh
Royal Johor
Rotal Perak
Kelab Di raja Pahang
Kelab Golf Putra
I have a friend staying in KL but join Kelab Golf Putra Perlis. Rahman Putra and KGNS have becoming his 'home' club, occasionally he played in RSGC - for about RM3000 membership, not a bad investment.
