In a dream scenario, my lineup would look a lot like the Walker Cup. Same as most peoples lists I’d assume.
IF money were not an issue, but still keeping up with size of modern Ryder Cups? Probably some of the older continental courses like Falkenstein, Morfontaine and Kennemer. In the UK definitely one in London - Sunningdale would work. Maybe a Pennard in Wales or Ballybunnion in Ireland. Anyplace the Open isn’t likely to go.
In the US - Camargo, Chicago and Shoal Creek would all work size wise. But I doubt any of those places would put up with the aggravation.
