They are pretty much static 10% for Disney owned. It does change occasionally like this past year with giving us 20% (which I hope they continue). The non-Disney owned have changed. It's always best to ask at every location QS or TS cause discounts can be added or taken away at anytime.
If you are a Disney Visa holder or DVC member, ask if they take any of these cause sometimes they take one and not the others and sometimes the discount varies by card.
