Cons:
A lot of fairway overlap, holes 2-6 all play across roughly the same ground making communication very key if there's even one other group at play. Also holes 2 and 5 play with the same pin and come from a similar direction... so again, communicate.
Some road/property danger with much of the course abutting a residential area and cars frequently parked just along the 'fairway' for hole 4.
Signage was often non-existant and in almost every case where the signs were still in place, the poles had fallen out of the ground and were propped against a tree or just lying around. Also, walking up to the course it was hard to tell it was even there, you have to do a little searching to find the baskets from the parking lot and even then, the first basket you'll see is for 9, not 1.
Some disc loss potential in the heavy vegetation especially around the pin for 4 and the little slough type creek.
Other Thoughts:
Downloading the map is a must, they don't have one on site and even if they did you'd need to check it about a dozen times to keep on track (alternately if you have a favorite local, that may be the way to go).
It's one of those courses that's not great, but it's fine if you know what you're getting into. Expect a rough game with a lot of "why did they lay this out like this" type of moments. Play it if you're around and it's still 2020 when the resort decided not to put in the pins for the mountain course this year. We played it twice almost for the shear oddity of it.
