If your looking to go through everything, including pictures and other misc things. 2hrs, allow yourself this much time as this place is beautiful. Had fun with the family and the people there were nice.
At least 1to 1 1/2 hour I would say. You might get through it fast but if you take your time at least this.
At least 2 hours for the ruins, film, and displays. Love this place!
Give yourself 2 hours to read everything, watch the short film, then to go through the actual ruins. One of my favorite sites to visit when I'm down that way and it's free!
