We visited the Queen Mary and did the basic passport for $25. Whilst I found the audio tour a little confusing to follow, the information was very good and is was fabulous just to wander around the decks. We were slightly sceptical about the Ghosts and Legends Tour but it was very well done and worth seeing. The most interesting bit however has to seeing the remaining propeller by actually leaving the ship to see it in the water (hard to explain in writing!).
Very good attraction and well worth a visit.
