To clarify further. Photopass is what has always been available. You can get new cards for free from any photographer around the park who takes your picture. Or, you can hand them a card you already have. After your trip, you can enter all these numbers into the photopass website, view your photos, crops, add borders, and order individuals prints or a CD of all your pics. If you order a CD, it costs $69.95 and you then have a digital copy of all your pics to make prints, photobooks, anything.
Photopass+ can be bought for $69.95 if you prepay before your trip, or $99.95 if you buy in the parks. With it, you get a gallery CD of stock photos and a special photopass+ card. (or if you prepay, you get a voucher to receive a + card in the park) You can hand this + card to any photopass photographer in the park, to have regular photopass pics taken and added to your card. In front of the castle, on main street, with a character, etc. You could also get and use a regular photopass card for these pics. With the + card, you can bring it to the ride photo checkout and have your ride photo added to the card. You cannot do this with a regular card. You can also show your + card at a participating dining restaurant to get the photo package that they normally offer for purchase for around $30. If you show your card, they give you the package "for free" and also put the pictures on your card. They don't take more pictures around the restaurant, just the regular picture that everyone takes in front. The difference is that you do not have to pay extra to purchase it and the pics are added to your card. Once you get home, you can enter your + card number, along with all your regular card numbers into the photopass website. Edit, crop, add borders, etc. Then, using the code inside your stock photo CD, you can order the CD of your pics "for free." It's the same CD that you would have ordered had you not gotten the +, but now it includes your ride and dining photos.
I've seen a lot of confusion on this. Hope that's clear and helps somewhat.
