In regards to DL advice for your visiting family... even though we go there quite often, we never have a plan. Since we have AP's we just go and enjoy the atmosphere and ride whatever we can. I will say that Carsland (in California Adventure) is a MUST, and get there early because the fastpasses go fast and the line gets long! You need to get Brooke to help you out as she had a fabulous trip report with some tips that even I didn't know about!

They will have a fabulous time. If they have ever been to WDW, it is such a different experience.
PS... My baby girl is at DL/CA tonight for gradnite. Their class is not very happy about being over run with all the Monster fans as it is open 24 hours and they don't want to share. At least they are closing most of CA for them so they will have a little Disney magic all to themselves! My DD's favorite place in all of Disney is Carsland, so that helped soothe her a little.
