Hello, Denise!
I have my PhotoPass CD code, from my PhotoPass + right in front of me, which states that PhotoPass + purchasers can do the following:
"2. Place a Disney's PhotoCD into your cart. Be sure to make any desired edits to your photos before ordering!
3. Enter the code below in the Promotion Code Field on the shopping cart page to remove the cost of one (1) Disney's PhotoCD from your order.
4. Complete the checkout process by following the online instructions."
As you can see, that CD is included as part of the PhotoPass + price and comes off as a credit in your cart when you order it after your trip.
Regarding PhotoPass photographers at Mickey's Very Merry Christmas Party, not only will they be there in full force, but they'll be able to capture so many magical memories for you even though the park will be dark! Some of my favorite photos from our Moms Panel Training Weekend are nighttime shots at MVMCP taken by the very talented PhotoPass photographers! They know just how to balance the light so that Guests and Cinderella Castle are perfectly lit.
At that time of year, I'd say that you'll be very pleased with your purchase of Disney's PhotoPass +. Don't forget to take advantage of the
Disney PhotoPass + pre-order offer, which saves you money, too.
Send more questions as you think of them; we love to help!
