I know that there will be plenty of photo op's while on the ship... I am a sucker for wanting to buy them all, but I am trying to stick to a tight budget. Do you know if they will take a few pics of our family with our own camera, when boarding the ship, with characters, at dinner etc??? I don't want to ask if it is "tacky" or rude. Is it okay to ask servers to take a family shot? TIA.
