Hannymom, my guess would be the private viewing areas that you get access to when you are on the WDW package plans (Discovery Magic, Deluxe Magic, Grand Plan). LAinSEA mentioned these areas in a post a month or two ago: click here to go to post (search for "viewing" and you'll find it). From what is stated on the Mousesavers site, it sounds like if you get a discount on the package, you won't get the coupons for the private viewing areas for parades/fireworks.
