It's kinda complicated because it depends on whether you have Wishes or Escape or Memories or Cruise and whether you use Disney for your wedding photography, AND whether you want hi-res images (prints up to 8 x 12) or archival images (prints up to 30 x 40)!
In your case, they would charge you $750 for the hi-res disc or $950 for the archival because you aren't using Disney photography for your event (Shutters on
DCL is an outside contractor). However, considering that many couples only get a handful of really great shots, you may prefer to purchase individual digital files at $25 each.
Alternatively, you can wait 3 years to buy the disc for $500.
