Photopass is the service involving photographers and the ability to purchase prints, digital downloads, and photo products.
The Photopass CD is a photo product that gives you the digital images of the pictures taken of you by the photopass photographers during your stay. When you do an order for just the CD, you get a limited rights release so you can print pictures or make scrapbooks, etc, for your personal use.
Photopass PLUS is:
The Photopass CD...
The print packages of the pictures taken by photopass photographers pre-seating at many character meals, AND the digital images of them...
The print packages for Pirate's League...
The digital images of the ride photos, as long as you claim them after the ride.
With the CD you have the right to print pictures wherever you want. A 5x7 printed by Photopass is about $15. A 5x7 printed by shutterfly is under a dollar (I think). It allows you the freedom to choose where you want to order those prints from.
