I'd go to England, April 1st, 1912 with a peroid-looking but modern tech video camera, a pressurized preservation case and some valuable items.
I'd sell/trade the valuable items for a 2nd class ticket aboard Titanic, and take footage of the stops in Europe, the near-miss with the New York, the sailing, shipboard life, crew, passengers, the iceberg, the evacuation, the bullshit in 3rd class, the sinking, the sounds of the dying in the water and the rescue.
Upon reaching New York, I'd put the tape/disc in the preservation case, hide that somewhere, and kill myself.
