Is this a doable side trip? We live on the east coast, so this would be our one big trip out west. Want to do 3-4 days at Disneyland, a day at Universal, a day at a Pacific Ocean beach and possibly the Grand Canyon. Would also love to see the Redwoods. How many days would you recommend for this trip? /We easily have 10 days , but 9 nights, but of course that includes the flight days. Anyone from the East Coast done this type of trip?
