We had the best time at the Great Lakes Science Center. We went for the special exhibit, The Titanic and also saw the Imax movie. Excellent - we were told it would take about 1 to 1 1/2 hours to see everything in the exhibit and were there for over 4 hours. We read everything. There were five of us - from 17 years old to 53 years old and are still talking about it and discussing it three days later. My young adult three sons are doing research on questions they have, conversations we've had and more!!! WELL WORTH THE MONEY!!!!!
