Unfortunately our one year + Daughter managed to lock herself in the comfort room, what followed was very upsetting, for her and her parents.
The lock which should have been able to be unlocked on our side with a coin, did not work, a member of staff, then starts to butcher the door in completely the wrong place causing unnecessary noise(upsetting daughter who was now in hysterics). Having been in situations like this before where I had to take charge and was eventually billed for the damage..!! So I stepped back and just gave advice, eventually she was released......and up to now we received no apology for distress, and inconvenience, the door was not able to be closed for the rest of the vacation...
