Hello everyone! First trip to California. Two semi-seniors who love nature, the ocean and are on a tight budget. We plan to stay couple days in San Francisco (looking for inexpensiveish lodging and things to do). Then 3 days in Yosemite staying in Curry Village. Will have 3 days left. Should we stay in different towns from Big Sur to Monterey? Or base in one town. Should we squeeze in Cambria/Paso Robles? Is third week of September a good time for whales/Monarchs? Soo many questions! Any assistance would be greatly appreciated. Hoping for a trip of a lifetime. May be only visit to California. Thank You!!!
