Agree pretty much with everyone else. About the only ones worth buying are the formal night ones. They will offer you some "specials" (which I never could quite figure out). Just buy the 8x10 of your formal nigh if it turns out nice and take alot of your own pics. I didn't find the photo staff on RCI to be super friendly or helpul especially when compared with the rest of the excellent staff.
I don't usually mind the picture taking but the pirate in the dining room was just plain tacky and annoying. Same pirate that we had to get taken with as we got off in Nassau...Not a very good make up job and just plain dumb.
