36 hole

Greetham Valley in the midlands has 2 x 18 hole courses and a little 9 hole course. It’s been a while since I was there but I think the 9 hole is a par 3 course.

They do a lot of society/group stuff there.

Where I play (Yeovil) we have one 18 full length and one 9 reasonably full length but shorter (two 5s three 4s and four 3s) when played as 18 it has slightly different tees for the back 9.
 
Up in Edinburgh Dalmahoy has 2 courses the championship East and much shorter resort West. @pled is a member there if memory serves me. I used to be a few years ago
