I have only been a member of inland links courses, good for winter golf and the perks of an inland course too! IMO the perfect compromise.
I have tried links golf and parkland both OK but I prefer the nice middle ground.
I never understand this term "inland links". Its either links or its not IMO. It may be on a sand base so it has fast running fairways and lightening greens but does it have all the gorse and straw and is it cut well into the landscape, I doubt it. Also links is unique due to the elements of the sea breeze/winds which is nothing like you can experience inland.
For me there is no such thing as "inland links", its heathland which is very nice and more testing than parkland and for me is what represents a links course as close as possible inland.
