Hi Jessica,
Wow! Now that's a family vacation! I'm a huge fan of
Disney Fine Art Photography, which offers professional photo sessions at Walt Disney World resorts and in some theme parks. My family of four has booked mini photo sessions twice, once at the Grand Floridian and once at the Polynesian Village Resort, and I've been thrilled with the results and the price.
Disney Fine Art Photography offers an enhanced photo session for up to 40 people that costs about $400. The session can be scheduled at a number of locations around
Walt Disney World. The price includes a disc with all your photos.
This package can be used at any resort hotel, Epcot, Animal Kingdom or Hollywood Studios. It is not available inside Magic Kingdom.
I hope that works for your family as well as it worked for mine. Thanks for visiting the Disney Parks Moms Panel. Please let us know if we can help with any more advice about visiting Walt Disney World with a large group. Enjoy!
Wilma
