I'm looking for advice on possibly touring Hwy 1 on the stretch between Monterey and Morro Bay. I'll be on a 6-day trip in early August. I've planned to stay nights 1 and 2 in Monterey, and must spend nights 5 and 6 in Sonoma. I am interested in seeing the Hearst Castle and wonder if it would be a good idea to try and drive from Monterey to San Simeon and back to Monterey in one day, or whether to plan an overnight in Cambria or Morro Bay before driving back north. How many hours to budget for the actual driving? I'm not sure.

Also I'd be interested in hearing about Hwy's 41 and 46 and whether or not it might be advisable to cross over between Hwy 1 and the 101 there for the return trip. Last year I took a most interesting trip between the 101 and Hwy 1 between Geyserville and Stewart's Point in Sonoma County, and found road conditions pretty adventurous...maybe a little too adventurous. Are 41 and 46 two-lane and paved? Thanks!
