Looks like you already got a lot of good information! Just wanted to add a quick note that if you would like assistance booking your trip, please contact me (travel agent - no additional cost to you!). We used to go to Disneyland and Universal a couple times a year before "switching" to WDW. We are visiting Disneyland in mid-September after the Disney cruise from Vancouver, BC to LA. Can't Wait!

If you book the Disneyland package, you can book the Universal tickets, airport shuttles, and Catalina Island (all with transportation from Disneyland) all in the same package. Would make it nice and easy!
