Oh yes, the old t-shirt, photo, shore ex. An oldie but a goodie. I can tell you without a doubt anything I buy onboard is MUCH more expensive than that.
When I was in club orange a couple brought their daughter into club orange. That child smacked a spoon against a glass the entire meal. The mother supplemented that with singing, repeating the same word over and over and saying nothing to the child about the spoon behavior. Contrast that with a couple that brought their child into Sel de mer. They were in there for a very LONG time. If I wouldn't have seen that child with my own eyes, I wouldn't have thought she was there. As I walked out, I said I hope you don't mind but I really admire how well behaved your child is. I wish all kids were like that.
