right though it has been two years since our last visit. I think we bought a princess themed frame at WDW that was for a 6X8 photo.
4 prints 4" by 6"
One print 6" by 8"
One print 6" by 8" of Cinderella Castle
Cinderella-themed photo holder
Two quick points:
1) the number of shots goes up after mutliples of 4 in your party and
2) There should be a photopass number on the large picture. You can add additional shots taken for your group to your photopass account.
