My wife and I toured a Titanic exhibit in Las Vegas three or four years ago. There were over 100 artifacts on display that had been recovered, a replica of the "Grand Staircase", newspaper clippings, and so on. The only real "recreation" they had was a section of the ship's deck that was maintained at approximately 31°F (the reported ambient temperature in the North Atlantic at the time Titanic struck the iceberg) to give visitors an idea of what the weather conditions were like on the night the ship sank. The final exhibit was a 25-foot-long scale model of the wreckage at the bottom of the North Atlantic (though they closed the distance considerably between the fore and aft debris fields). It was definitely worth seeing and, as you stated, respectfully presented.
