Growing up and living in DC, with huge fireworks on the Mall every Independence Day, I can definitely say the most incredible fireworks I have ever seen were in EPCOT, Illumination, this past Christmas visit...it was like the sky had been torn, shredded into pieces, and the resulting vacuum was engulfing the Earth and swallowing the known world whole in a cosmic cauldron that was taking you body and soul to a different dimension of existence.
Nah, Wishes.
Kidding, that Illuminations was sincerely incredible and memorable. Final answer.
