We booked on 3 of the tours but didn't do the ghost one. The first tour was the glory days of the liner. Our guide was so unusual but informative and funny. Fabulous experience. The 2nd was a tour of engine, boilers, structure and prop. Disappointed that a lot had been removed but seeing the prop was amazing. You are 25 feet under the water line on the tour. A spooky experience. Well worth $100 for the two of us. My only gripe is that the grand old lady of the seas needs some tlc.
