The Ocean Course at Cabo del Sol is a must, it's an excellent golf course. The recent housing build-up around some of the perimeter detracts a little but it's still a great course. An excellent group of par 3's and some very interesting risk/reward holes. Plus, some great fish tacos just after the turn....
Querencia is also a very good course if access is available. They used to have allow play for guests at Las Ventanas al Paraiso, not sure if that's still the case. It's one of my favorite Fazio courses. Gil Hanse will be doing the second course at Querencia, that's the one that I really look forward to seeing in the future.
