I liked the slopes on the 14th green of the Dunes. Particularly the rise and fall from the left side and back of the green to the front and right side. If you play away from the ocean on your tee shot then you really have your work cut out for you to get down in two.
A chip from short left or a putt from the left half of the green require great touch to get the right pace, and with the ocean staring right at you from behind it's easy to get tentative and leave your shot short of the ridge altogether, which just means you have to deal with it yet again on your third shot. There was also a lot more break to the right than I expected on putts from the left half of the green to the right.
