I'll have to be honest and say that when we drove past Grumpy's and the kids asked to go, I thought it would be really lame as all the holes are packed into such a small space.
I couldn't have been more wrong.
Grumpy's more than makes up for it's small space with entertaining little quirks on the holes.
The course is immaculately kept and obviously well looked after. The paint was bright and cheerful.
The kids loved it so much we played twice during our stay.

Only thing I would suggest is they make a family pass price to make it more affordable. From memory at $11 per adult and $9 per child, $40 for a family of 4 I found quite expensive.
