It all depends on the airport operator.
If they go with the school your stuffed if they don`t care basically your the pic so you decide. It all hinges if they are going to stop you flying there if you don`t do it as the school does.
If they don`t care tell the school to piss off. But have a chat with a more experenced pilot just to make sure its not you being stupid.
At the moment we can`t really say if the school are just being difficult due to some grumpy auld sod of a cfi or your doing something daft.
