Sailing next wk with my son who will be turning 3 on the cruise and my 6 month old daughter. Planning to bite the bullet and spend the $500 for the photo cd and prints. I want to make sure We get the most out of it and take some family shots and of course ones of the kids. Do they take pictures every evening and what time do they start? What are the background options? Do they do any "magic" photos like they do at WDW like add Tinkerbell, etc. into the picture? Any tips for getting the best value out of the CD?
