We've also been planning our July 2007 (July 28 - August 11) trip for a LLOONNGG time! It was supposed to be a June 2006 trip, but we ended up moving out of state instead during that time so it got pushed back by over a year.
Just a heads up. I ordered my maps awhile ago and read all the posts on here about people getting an email about them so they knew to expect them. I got the maps this week (I think they're REALLY nice and can't believe people are complaining about them!) and got the email about 3 hours later!
Good luck - when exactly are you going?
