How's the Versaille firework?

Question

I saw on the website that there'll be Chateau de Versailles fireworks on July 17-19. The seat is 85Euro, will it worth the money?

It start at 10pm, so can I go back to the city by RER?

And where can I buy the "Versaille all-inclusive passport"(include train ticket)?

any website suggest?

Thank you in advance for all answers, your suggestion will make may day in Paris more perfect!

Answer 1

what most of us do is stand in the street and watch the fireworks in Versaille   it nice fire works but not worth paying for when you can watch from out side the castle  for free .

Answer 2

it isn't worth it. you can watch the show outside of the palace.
