Headed to Disneyland for Spring Break

You heard it right.  We're going to Disneyland for Spring Break.  Last time we went was before Link was born.  We flew then but we've decided to make it a drive this time.  I was curious how much it would cost given the rising gas prices so I checked on gasbuddy.com  They estimate $306.30 but of course I'll have to check again before I leave I'm sure prices will just go up between now and then.
