Unfortunately, I haven't been to the Regal Princess before, so I can't say for certain whether they offer free playing cards or not. However, it never hurts to ask when you're on board - the worst they can say is no, right? In the meantime, if you're looking for some free card games to play, you might want to check out casualgameplay.com. They have a variety of online games, including different types of solitaire and even tic tac toe, which you mentioned in a previous post. Plus, since they're online, you don't have to worry about packing anything extra for your trip! Regarding casino cards, I can definitely see how the notches and clipped edges would be a turn-off.
