I bought my boyfriend a membership for his 25th birthday (price of 2 admissions). When we went to use his membership, they allowed me entry free of charge! We had a fantastic time on both the fighter jet and space shuttle simulators.. as well as the hot-air balloon ride (much more fun than it looks)! We also enjoyed the 4D theater and the beautiful mural! They have a fantastic museum in the second building showcasing many of the old planes and equipment used by the military. It took us well over three hours to explore the museum and we aren't the type to linger. It was a great experience and he loves being able to go back and play with the simulators when he has free time!
