Hi, Abbie!
In short, yes, most of the attraction photos available at Walt Disney World
will be included on your
PhotoPass + account, so if you're interested in purchasing them I suggest that you take advantage of the pre-order discounted rate of $169.95.
Even without the Dining photo packages, having access to all of your PhotoPass pics, in addition to the Attraction photos will be a huge money-saver for you. Imagine pics of your group in front of each of the spectacular WDW icons, as well as from the attractions you mention, too. You'll be so happy to have access to all of them, at one discounted price, in addition to being able to use these pics however you'd like.
Have a great trip! Be sure to send more questions as you think of them, too. We love to help!
