Hi Arlene!
It is wonderful to hear from you again! A pre-and post-cruise stay at the Polynesian plus a Disney Dream cruise sounds absolutely fabulous! Your experience is sure to be magical with being able to enjoy the magic of Disney on both land and sea!
The Photopass CD is a great option for your Walt Disney World stay, but unfortunately it can't be linked to your photos on the Dream. My advice for your resort visit is for everyone to get their own individual card because you do have the option to combine multiple cards into one account online. This makes it very easy for parties such as yours to share all the fantastic photos taken during your stay.
On the ship, you can pre-purchase your
Photo Package before you set sail, but your pictures can not be combined on one card on the cruise. Each stateroom does have to purchase their own picture package or CD. But, if you take a lot of group photos, each stateroom will have copies in their stateroom folio. Pictures are available for viewing each evening between 5:00-11:00pm in Shutters. Just like at WDW, the Disney Cruise Line Photographers do a phenomenal job capturing priceless cruise memories!
I hope you have a fantastic time on your surf and turf adventure! Please continue to let me know if you have further questions! I'd love to help!
Bon Voyage!
Nancy
