For those of us meeting in San Jose, I just received the following from a friend that lives in Paso Robles. Sounds like Cambria might be a good place to rest for a minute or so.
HIGHWAY 1 ??? What a ball buster drive!! I guess that's what guys in car clubs do however---they go where no one else will be!! Yes, at Salinas you go over to the coast on 68 and then head south past Monterey and Carmel and just keep going. A couple hours later and you will get to Hearst Castle area and then 11 miles after that and you come to Cambria which is a wonderful little beach town except you won't see it unless you get off the freeway and go through Cambria. That detour would add only about 1/2 mile to your overall voyage. You can get off at the north end of town, go through the town and get back on Highway 1 at the south end of town. If you want to stop for lunch, get off at the north end of Cambria (Moonstone Beach) and make an immediate right turn which takes you along the ocean front and a bunch of nice small hotels. You could have lunch (after your windy, twisty gut-wrenching drive) along the ocean. Anyway, when you are back on 1, go 4 more miles south on 1 and you'll come to the 46 west turn off to Paso. From there it is about 23 miles over the mountains into the south end of Paso. As you get close to Paso, you will go past about 20 wineries. If you drink wine, plan to stop at least at Castoro--it'll be on the right side and very clearly marked about 2 miles before Paso. Then, the easiest thing to do (for you as a visitor) is to stay on 46 and get on 101 NORTH and get off at the Spring Street exit (the first one) and then travel right through the center of town to the hotel which is at the north end of town. This way you go under the sign about you guys and also past the Park which is where I presume your event will be. Spring St exit off 101 is basically 1st streeet and they are numbered up to 36 from there.
