LOL! OMG, that would be the perfect tie-in, why they're out there in the first place! Brilliant idea!

I also rewatched parts of Heart yesterday and was reminded that near the beginning, after Sam asks Dean if he can be a bigger geek about hunting a werewolf and then says "Okay, Sparky! And after we kill it we can go to Disneyland." Now the way things turned out could definitely change those plans, but it could be another reason why they head to Hollywood.
