I haven't made the trip to Cabot yet and it was for this very reason...... I followed the construction news of Cabot Cliffs and judging by pics, timeline, etc. it seemed like they were offering 'preview' rounds very early. Also, that region had a harsh winter so the roots are still probably not that strong. A Canadian customer of mine informed me that the course will need time to heal and that it may be wise to wait 2 seasons before I make the trip.
I have the same concern about going up to Forest Dunes and playing the Loop. Seems the ownership pushed the course out into play very quickly. Conversely, Streamsong resort seems to be taking a more conservative approach as their Black course opening is pushed back much farther. It will have a full year of grow in before the preview rounds begin late fall 2017.
As a businessman/business owner, I understand the need to push the opening of a course up to keep the 'buzz' going, but for long-term benefits, allowing the course roots to take hold for an extra season is a proven better decision (especially in harsher climates). Unfortunately, all business areas have moved to the "rush to make money immediately" as opposed to the smarter long term business model which is "steady organic growth". Time is money but taking your time yields a better product.
