No they don't have Birthday discounts, but it's worth the price.
They have senior and military that I know of.
Not that I am aware.
And check with the place you're staying we got discount tickets where we stayed
No birthday discount listed, that does not mean ask for it while looking sad next to your grandson!
No but is only 25$. And 20 got seniors
