4 different courses for sure. Here's my rankings:
1. Fazio Foothills - great use of the natural terrain. Difficult
2. Fazio Canyons - short drive from the resort. Awesome views, gorgeous course... a little more open/forgiving, especially around the greens.
3. Palmer Lakeside - Nice, but a long drive from the resort. 30+ minutes.
4. Coore Crenshaw - pretty standard resort course. Some nice holes, some nice views but nothing too remarkable.
I used to get to play all 4 often and I would play all 4 any day of the week for the $0 it usually cost me, but the fazio courses would be the top 2 for sure.
