We have the yearly PASS for 4 years now. Not because it's really great, but simply because we are just in neighborhood and it’s a spacious playground for children. During these four years we come and go, what we experienced today was the worst. Ticketing: Cité des enfants 12€, Explora 12€ ..There is combination that are cheaper too. Annual pass cost 95€ now. In general, Cité des enfants was quite alright, kids have fun. BUT to be honest, it lacks of variations, lack of choices to do, with many broken machines..If we don’t have the yearly pass, I would not spend the money for a children session, too expensive for those broken machines. Since once again, it’s in our neighborhood, my children go there to have fun for half an hour, to play the all same games they like. That’s all. So today was the worst visit, for a simple reason. The man at scanning ticket line for Explora. Our cards are valid until November 2016, even though it’s written until August 2016. Last year, Cité had fire and they had to close the Cité for renovation. So, as members, we got 3 months extension. WE never have had problem with our cards even though the extended validity is not written on our cards. I suppose that the employees are informed about this. Today was bad luck. After the 6 m queue the scanning ticket man refused to let us in, so I went to check it out at ticketing who said that our cards ARE VALID! We went back and forth 4 times! When I decided that it was enough, I asked his name so I could make official complaint to Cité des Sciences. He refused, so I took out my phone to take picture, he came to stop me violently, he was about to hit me! My children were children, begging him to not hurt me! Impressive! The managers came and surrounded me as if I were the criminal who didn’t pay! It was ridiculous and unnecessary. Our cards were valid this morning for us to go to Cité des enfants, if they have some error on their system, they supposed to check on it, and not blaming on customers! The nice ticketing lady couldn’t help much. If they really need us to provide tickets to EXPLORA, then, they should have made it available for online ticketing! Just like how they did with Cité des enfants. We booked the ticket online each time, paid nothing as we have the yearly PASS. The EXPLORA is not available to be booked online for those who have yearly pass, because they usually let us in when we show them our member cards. Somehow there is a bunch on uninformed employees who instead of getting themselves informed, chose to argue with customers with valid membership! Yeap, it only happens in France. And come on, we are in France, that scanning ticket man and manager kept talking in other language --- I don’t know whether it’s Algerian or Moroccan. Note well, I didn’t take his picture, got my phone checked by the security guy. Review your attitudes, monsieurs. I don’t know where exactly was wrong with them and their system. I do believe that the manager, who lower down his tone at the end, knew that he was wrong but refuse to acknowledge it. The scanning ticket guy was simply ignorant; he was not well informed to let extended membership people in or simply new employee. As simple as that. And the end, the higher rank manager took us to go up by lift, arrogantly ignoring us. Yeap. Review your customer service attitude, please. I know that what we experienced today won’t make any change for them. But honestly, don’t waste your money, your energy for mediocre Cité des sciences with their arrogant ignorant employees.
