I agree with Tom. You're playing 3 terrific courses, Cordevalle would be fourth, though I like it and think that it's worth playing...it's a strong RTJ Jr. course in a nice but somewhat arid setting. The facilities are very, very nice, it's a cross between a private member course and luxury resort....nice clubhouse, pool, sauna, great food.
If you're playing Pasatiempo and MPCC, you're already making the drive south to the general area, with Cordevalle being about a 50 minute drive south and east across the mountains from Pasatiempo, and about the same distance north and east from MPCC.
Though Cordevalle is good, there are a few other options in the area that are definitely a step up. If you're playing Olympic, you're not too far from San Francisco Golf Club, which would be great if you could get on. And from MPCC, you're quite close to Spyglass Hill, which is public though very pricey. Speaking of pricey, you can sometimes get on Pebble by calling really early in the morning the same day, it's also right next to MPCC. I also personally prefer nearby Spanish Bay and its ocean views to Cordevalle, but a lot of folks would disagree with me on that one.
You've got a terrific trip planned, you'll enjoy yourself with any of these options.
