Hi, Karen!
The PhotoPass PhotoCD that you purchased in 2011 is
not the same as the new PhotoPass+ service. What is similar between the two types of
Disney PhotoPass services is unlimited PhotoPass photos in your account, the ability to customize your photos with special Disney borders, and the really cool Magic Shots (with Disney characters!) available at the four theme parks.
The main difference (and reason for the higher cost) is that the
PhotoPass+ service includes photos taken on select attractions and at select dining locations. The "regular" PhotoCD is also still available, but this service does not include the specific ride and restaurant photos. So, the best way to take full advantage of your PhotoPass+ is to experience the specific attractions (mainly the "thrill rides") and dine at the specific restaurants (mainly the character dining locations) where the photos are bundled in the cost of the PhotoPass+ service.
I hope this helps! Please don't hesitate to write me back with any other questions you may have.
Wishing you a
magical vacation!
