Andy-
The lodging at Orange County National is very reasonable and you can walk to the first tee. We stay there every year with our group of 12. We get a package with a party room where everyone can hang out and play gin or watch a game at night.
Our M.O. is walk over for breakfast, play 18, meet for lunch and settle up, go to the nine hole executive course, The Tooth, for a scramble, go to party room and play gin. Wake up - repeat.
Ill second the recommendation of El Campeon.
