is there a golf course at centre parcs - sherwood forest?

No, just a range.

The one in Suffolk, Elvedon Forest does. I've played it a few times, the first is nice. There is a silly green on hole 3 or 4 or something. The one down the back is very narrow and tough, broke a run of pars with a bogey there last time Finished with a par IIRC, 7 pars 2 bogeys.

I would prefer if they have a simulator, less busy than a course and not weather dependant.

Take your own clubs as theirs are horrific! As are the balls.
