The city tour was very interesting but the NASA tour was amazing.highly recommend going there.
Unfortunately our bus broke down coming home, we were left sitting on the edge of the motorway for over an hour, not feeling very safe, 10 passengers. The trucks and bigger vehicles, were extremely close and we felt movement as they passed. The driver did not keep us informed at all. In hindsight we should have disembarked and gone down the bank and across to the shopping centre, given a coffee or water until our new transport arrived, most certainly gotten off the bus.
