10The Titanic-Lover's Cruise
In April 2012, a British cruise line celebrated the 100th anniversary of the infamous sinking of the Titanic. The MS Balmoral Titanic Memorial Cruise sailed out of Southampton, U.K. and took an identical route to New York City. Thankfully, this time the ship arrived at its destination without incident.
On board the memorial cruise, passengers were served authentic meals and listened to period-appropriate music. The memorial ship carried 1,309 passengers (not counting crew), the same number of passengers as the original sailing. Many passengers showed up at the port wearing period costumes, and 50 of the passengers were directly related to someone who had been on the Titanic on her sole journey in 1912.
A memorial service took place on board at the time of the original ship's sinking.
