Over half the exhibits were not working. Very frustrating that there is no guide pamphlet so to plan the day. Very long lines for everything and at 2:00 we got in line for tram to the training center we were told the line was 2 hours and the tour was 1 hour so to prepare for 3 hours. At 3 o clock we were told we would not make the last last tram ride to the training center. Why couldn t I have been told that an hour earlier. I downloaded the APP so to experience the center better and it only worked once the whole trip. Ridiculous price for nothing Very disappointing.
