My family bought a gold membership. So far we have used the membership very well. The imax movies are free and so is parking. We book the imax movies online so it is convenient when we get there. We usually watch a movie first and then go around and visit the rest of the science center. The favorite for the kids is the rain-forest exhibit. The like the waterfall and the change in climate. The kid spark exhibit is also a favourite for us. As for our older child she just tags along with us. So far we have seen 4 of the six imax movies. Don't know what we are going to do once the movies are all watched as this was our routine. I guess we could just browse the science center. They should maybe put in some kids movies on Saturday and Sunday even if it is not full screen. Just a suggestion.
