I am a Memphian and had never been to Stax until recently. It is a hidden gem that should be one of the top 3 things you go to here. I would allocate 1.5 to 2 hours. There is an abundant amount of info to read and watch. I would suspect children would find it that interesting, but if you love music or are age 40 or above you will remember the songs and love the videos from Soul Train that are being shown constantly of the artists.
