Howdy Stefanie!
PhotoPass+ is fabulous and has become a must have item for our Walt Disney World vacations!
Currently, if you order PhotoPass+ at least 14 days in advance of your vacation, you can purchase it for $149 (compared to $199.95).
I believe I saw that you will be visiting in August so you have plenty of time before your vacation to purchase it if you decide it will be a good fit for your family.
With PhotoPass+ you enjoy unlimited PhotoPass photos in your account, the ability to customize your photos with fun Disney borders, Magic Shot photos, Photos from select dining locations, Photos from select attractions, Photos from other Disney experiences and your Disney PhotoPass+ card for Photographers to recognize.
If you purchase PhotoPass+, a voucher will be sent to your home. Be sure to include the voucher with your important travel documents as you will need it to pick up your PhotoPass+ card. Once you arrive at Disney World, stop by one of the Camera Centers and pick up your pass. There are PhotoPass Photographers positioned throughout the Disney Parks ready to capture your magical memories. When you arrive home, you will use the code provided to you to order your PhotoPass+ CD. You will receive all of the pictures associated with your PhotoPass account as well as a copyright release so you may use the photos as you wish. PhotoPass is wonderful and has enabled us to capture thousands of memories over our past few years.
If you have any further questions about PhotoPass+ or need any other information as you are planning your vacation, please let me know. Thanks so much for your question and have a magical day!
