Hi Leslie,
Wow, with 10 days you are sure to immerse yourself in the magic of Walt Disney World and The BoardWalk Inn is an amazing resort that you are sure to fall in love with.
I, personally, love PhotoPass since I am usually behind the camera in most of our family photos and with this service, I can be in many of our vacation photos.
Memory Maker just recently replaced PhotoPass+ and is an all digital package. This makes it very convenient and you don't have to wait for a PhotoCD to arrive.
Memory Maker includes photos from select attractions, dining locations and unlimited photos taken PhotoPass photographers around all four theme parks. I think it would be totally worth the purchase since you will be there for 10 days.
Keep in mind that if you pre-purchase at least 3 days prior to your leaving for Walt Disney World, you can get a discounted price. It is all linked to your vacation package and My Disney Experience.
I hope you have a wonderful trip this coming spring. It'll be here before you can say "supercalifragilisticexpialidocious!'
Say cheese,
~Allison L
