Pete,
If you're looking for an extra round on the way back. I would suggest Northumberland Links in Pugwash, from all accounts it's a great course. Honestly, my only reaction to walking Green Gables was a deep sadness as McBroom successfully demolished a majority of the Thompson in the course. If you're going go walk the old dunes holes to imagine the majesty of what Thompson did there.
PS
I am the second in the game at Highlands. Maybe depending on how things go with projects at work.
