When you take the Titanic Experience in Cobh, Ireland, you will be given a ticket with a real name on it. The name belongs to one of the passengers on board the famous ship. Through the journey, you will find out if you (i.e. the person in the ticket) lived or died.
Here is the ticket I was given and the fate of the person whose name I was given. I quite rather liked it. It made the whole experience fun, even though I was sad to find her sad story.
