I asked this question a couple weeks ago and apparently it varies by the office. I called our office, who only sold a 4 day park hopper. But, they could order anything for me that I wanted. Their prices were exactly the same as the Disney website. Theoretically if you order from them, you get the
AAA parking pass which allows you to park in the closer AAA parking (not get free parking). But they don't have the 2007 ones yet, and no one could even guarantee they would get any. There are a few better websites out there that get you a slight discount, but for 5 of us getting park hoppers/water fun options for 10 days, I found a total difference of $15. So I think the people saying that they saved like $400 must be comparing to gate prices, not advance purchase, or maybe non-expiring (which we aren't getting) makes a huge difference.
