We got the $45 deal for both the bodies exhibit and the Titanic museum and thought the experience was worth the price. If you're not into biology, anatomy, or just sciences in general, I wouldn't visit. The exhibit is not for the weak hearted as you're likely going to feel sick at the sight of a 36 week old fetus exhibit.
Otherwise, if you're curious like myself and love biology, this is your place. Reserve about an hour or so in your schedule to get you plenty of time to read the notes on the artifacts. There is also a staff member on site who will help you with any questions, which I thought was nice.
