Sorry in advance for the long response...
We were on the 5/29 Dream Double Dip and I was dead set against buying the CD, but we got some absolutely perfect ops w/ the characters (my son in his Mr. Incredible's costume standing next to Mr. Incredible himself), and I had to do it.
The cost was $249. I asked the resolution question from the Shutter's staff, and they said that they would be the same resolution that they use on the ship, which looked great to me. (I'm on vacation, so I don't have the images with me to check).
We loved the book idea, but instead of buying their book, we came home & did one thru Snapfish. I redeemed My Coke Rewards point for a 8 1/2" X 11" book and just had to pay for shipping (about $6). It came out so good, I redeemed more points & bought another for my Mom.
In the book, I blew up several of the photos to full page size, and they came out great. If we had any of the formal photos taken, I may have wanted to print a larger size, but that wasn't the case.
I, too, was disappointed that there weren't more ops for candid photos on the ship. Last year, our favorite pics were the candids from Castaway Cay, but this time, even though we were there 2X, we only saw one photographer on the beach and she never made it down our way.
We have a decent point & shoot camera, and would usually take our own photos as well, but they were never nearly as good as the Shutters pics.
Also, we had two rooms - althought this isnt' the way we slept, we had my husband, son & sister-in-law in one room, and my mother, daughter and me in another. I bought the CD on my room, so it included any photo that my Mom, daughter and I were in, plus my husband and son. The only ones that weren't included were any that my sister-in-law was in by herself (and there weren't any). As far as we can remember, we ended up with all of our pics. (I would recommend checking your shutters folder & online several times, as there were a few in our binder that didn't belong to us, and a couple of printed ones that we didn't see online.) We were told by the manager that anything that showed up on the computer would be on the CD, and when you pick up the CD, they give you a printed sheet showing thumbnails of all the images.
Happy cruising!
