The photopass disk is a great value. Do a search here for "photopass" threads and you will see lots of opinions about it. I have posted in the past where there are a lot of great spots around the parks that you can get your pic done thats not at character m&g's or park entrances. There are also "magic shots" you can ask the photographers to do (some do them, some don't) and thats where you get Tink in your hand, balloons in your hand, baby Simba in your arms, Stitch popping out of the ground, Micky, MInnie, Stitch or Lilo on a bench next to you, etc. These are all images they electronically impose over the shot before you see it. They make for really fun, interesting photos! My avatar pic here is me and my DH with Mickey and friends "Soarin'" over us at Epcot! I love that one! Anyway, we have a 2 year old who adores the characters, so alot of our photopass pics are character pics, but for sure you can load it up with awesome pics at lots of locations around the world. Even at the Disney hotels at times they have photographers set up to take nice, formal pics on your pass. I definitely recommend it. We have gotten 554 on one disk in the past and we just went last week and got almost 200, but we are going back with friends in a couple weeks and are using the same photopass. We are going to break our record I think!
When you think about how much ONE picture costs and compare it to pre-buying the disk, its totally worth it. If you went ahead and picked out 4 or 5 pics you really, really liked and bought them, you may as well have bought the whole disk and gotten ALL of them for the same price.
