I have to get one of my special needs clients up to the top floor of a castle to complete this exercise. The way up is through the stone fireplace but I know he will panic and besides he's far too big to fit through. I complain about the lack of access stating that it is akin to banning him from joining in. The castle keeper takes me upstairs and lifts up two trap doors cut into the wooden floor. "He can come up in the lift," he tells me.
