Hi Andrea,
Thanks for your question! I am a huge fan of Disney's PhotoPass and PhotoPass+ services. The photographers are absolutely amazing and the memories they capture are priceless to my family and I.
You do not have to purchase any PhotoPass product before arriving at Walt Disney World Resort. If you choose to wait until you arrive at Walt Disney World simply ask a photographer for a card and begin to use it. When you visit the PhotoPass website or one of the many
camera centers located at Walt Disney World Resort, you can view and order Disney's Photo CD of all your images, or choose the shots you would like to purchase individually.
With that said,
pre-ordering your PhotoPass or PhotoPass+ can offer significant savings. If the best option for your family is the PhotoPass, you can pre-order anytime. You will receive a credit on your account and when you get home simply visit the website. There you can add your PhotoPass card number, and then choose to add Disney's Photo CD to your cart.
However, if you decide the PhotoPass+ is the better option for your family, you will need to pre-order at least 14 days before your vacation. This will allow enough time for the product to be shipped to your home. When you arrive at Walt Disney World Resort, you will need to bring the voucher you receive to one of the Camera Centers to pick up your PhotoPass+ card.
I hope that answers your question Andrea. Enjoy capturing magical memories!
