Welcome to the forum!
Our 1st choice school usually admits 210 pupils however in 2014 they agreed 20 extra allocations plus 4 appeals, so they made room for an extra 24! They have only admitted 210 this year so I am thinking that I can question why they are unable to admit extra this year.
The extra 20 could be a good point, as it's something they chose to do.
However, they had no choice in admitting the 4 appellants.
*1st choice is suitable to my daughters individual learning needs
Have you had a meeting with the SenCo at the school in question to discuss your daughter's needs and how they might help? (This might impress an appeal panel.)
*1st choice specialism in business, DD has great passion for this.
Hope you have evidence to support this.
*1st choice admitted extra last year
This shouldn't be part of your own case. It's a question you should put when the school's case is being discussed.
* Logistics at the end of school to her dance school
I'd only mention this very briefly. To be honest, I don't think an appeal panel would give 'convenience' all that much weight.
Evidence: CAHMS therapist has agreed to write a letter of support and be at the appeal if necessary. Headteacher will write support letter and appear at appeal.
Do I stand a chance? are My arguments valid?
I doubt anyone can tell you what your chances are. It depends to some extent on factors outside your control - how strong a case the school puts forward to resist further admissions. how many other appellants there are, how strong a case they themselves are putting forward.

But yes, you do have a case worthy of consideration, especially if there is plenty of evidence as to why this particular school would be best for your daughter's needs.
