Nearly forgot...good shout.
Singing hills is fantastic value for twilight, a real gem of a course and for £12 at weekend twilight, its great. Challenging but you wont get a better course in sussex for the money.
The fact its 3pm aswell or 2pm on a saturday makes it even more appealing. You will of course definately both need your golf shoes etc, whereas at places like Waterhall and Benfield you get away without. It is challenging as byf says, but for £12 you must give it a shot while the twighlight fee's are about.
I need to get out and have a round soon, then i can get back up there when i've sorted my game out a bit. Has anyone been up to Hollingbury or Waterhall later on in the evening? Only want to play 3 or 4 holes a couple of evenings without paying £10 to see how i play.
