Appeals of this sort are only concerned with the facts of the situation and the applicable law.
I assume that you have received holiday pay because you did not take the time off, the only suggestion I have is that you argue that this money should be averaged across your earnings, but this assumes that it would bring you back under the allowance, if it doesn't then I don't know what other argument you could put forward.
