Day 9 is a bit ambitious, make sure you have Getty Villa booked well in advance because they have limited access IIRC. Have a backup plan. Getty Museum on the 405 is more along the route you'll take to your eventual overnight destination at the Beverly Hills Hotel.
Day 12 "drive 1 hour to Anaheim" bwahahahaha
Day 13 and 14 - You will be at Disneyland Resort in the middle of summer vacation season and Star Wars Land is set to open May 31st. Be ready for crowds, will need reservation for Star Wars Land, may be automatic since you're staying on property but you should confirm. I'd skip Catalina island on Day 15 and use that to catch whatever you didn't make it to at the two parks.
