I'm sure this must have been suggested before but a practice area with a driving range and couple of greens would be great.
A chance to get used to new clubs or practice putting would really help. There could be a practice area in the 'choose a course' with a driving range and a green or two, one flat one on a gradient.
I have tried practice putting just going round a green but it ruins your overall score.
Please look further into this. Thanks
