No offence Frank but I would skip the Lakes as Cabot and Highlands Links are World top 100 and the Lakes is nowhere near that class.
It would take a lot more than that to offend me Wayne
That said, I'm the type of guy that likes to see as many golf courses and regions as I can. I understand your point of view, they are surely World Top 100's, but if I'm not returning or not going to return anytime in the foreseeable future, I would try to add an extra round at a different golf course and experience a different region and a little more of the slice of heaven that is Cape Breton.
Additionally, I should have mentioned this in my last post, if you want a golf course that's a bit more convenient to get to (along the way to Highlands via the Cabot Trail) and a unique play on the island, play Cabot early morning, than drive over and play Le Portage, then make your way to Highlands Links along the Cabot Trail. You could actually add two additional courses (Le Portage and Lakes) if you do this with my suggested itinerary above. So my schedule would look like this:
Sunday - Play 36 Cabot
Monday - Early morning: Cabot, After lunch: Le Portage, then drive over to Highlands Links with a glorious setting sun.
Tuesday - Early morning Highlands Links, Afternoon: The Lakes
Again, this is taking in my preference for seeing as many regions and golf courses as possible.
Also, as you leave Cheticamp make sure to stop at Aucoin Bakery. They make awesome stuff and perfect to snack on while stopping at the various scenic outlooks along the trail...I love that place.
