If Disneyland Paris are still doing their 'upgrade your ticker to an Annual Passport for 35 Euro's' offer I may consider a purchase if I book a trip.
Last year, we also got Magic Mountain passes, and made it up there a few times. It is a good value (especially for the boys, wanting more on the thrill level), but gets hard to make the trip up there, just to watch them ride.
Disney related gifts are always easy to add in, too. Having the annual pass discount helps - even more this year with the company offering 20 percent of to all pass holders for a couple of months. Also, there is a Disney outlet store just down the street in Fullerton. It has discontinued and other things from promotions that are barely over.
Gift cards for the park usually end up in stockings, too.
