Just be aware that if you don't buy the CD, to order the pictures separately it is $15 for 2 4X6, $15 for 1 5X7 and $17 for an 8X10, each (or $15 for a digital download of any of the sizes, instead of a physical photo). DD loves visiting characters so we usually come back with well over 100 photos in our account, and this trip it was over 300 photos. You can always buy the photopass CD when you get home, but you won't get the discounted price.
Also, if you are interested in ride photos or photos from meals that sell them (not Akershus or CRT where they are part of the price), you will have to buy those physical photos separately during your trip as you can not get photopass+ after your trip. Once you have bought them, there will be numbers on the photo's border (and usually on your receipt) where you can add them to your photopass account.
