In Malaysia they use the Reclub App to arrange social games and make the payments for shared courts.
There are many Hosts who rent the courts (all indoors and some even air conditioned! Sheer bliss compared with the courts I usually play on in Lombok) and then advertise social games and anyone can join.
So today I played for 3 hours in the morning and again for 3 hours in the late afternoon/evening.
Wow! Malaysia is my pickleball heaven!!
