I remember Ian Andrew mentioning to me that #4 is one of the best uphill par fours in Canada (I think it was #4). Although private, a thoughtful email to club management will likely result in access (that’s what I did).
3rd hole is a personal favourite, there's a half a dozen great holes on that course, just short ...
Of note: not all of it was done by Stanley Thompson, but a fun course to play and recommended.
Keltic Lodge
Corson House is fine, was renovated, stayed there last year and thought it was good.
Food
Neil's Harbour chowder on you drive around Cabot
Coastal Burger if you want High cholesterol
Charlottetown has many great places to eat
Alma Lobster Shop in Fundy (best Lobster Roll I have every eaten ... ever)
5 Fisherman in Halifax
Hikes
Ben Franny is tough, but extremely enjoyable if you like a tough hike.
Skyline Loop is the easiest and has a spectacular view, parking is tough in the summer
Golf
Consider Antigonish as an alternative, I happen to like Lingan in Sydney too
Fundy Park (9 holes) is awesome
Life Beyond Golf ...
Surfing
Can surf at Ingonish!
You can surf the Tidal Bore too!
Whale watching depending on season
Parks
Arsaig Provincial Park (NS) is really cool
Greenwich Dunes, Stanhope Beach are fabulous in PEI
Fundy National in NB, Hopewell Rocks (both are must see's)
Fishing
Brook Trout in NS, Salmon in NB, lots of fly fishing options
People are incredible, mix golf and scenery and you'll get a better trip.
