Light Shows / Fireworks Schedule to Plan Park Reservations ~ HELP

[My Grandpa]

Not sure if this is the "best" or the "right" place to post, but ..... In upcoming late April. Typical Tribe of 7: 3 Grand Kids, 2 Kids and 2 Oldsters. We WANT to Plan & Make Reservations ~ but are hung-up on nighttime events. WHERE and typically when can we find a schedule of the nighttime light shows / fireworks displays after at MK, AK and Epcot? Has a night show replaced, was it Fantasmic(?) at DHS?

For the other 6, cost was a simple issue ~ so they went with the 1~Park~a~Day ticks. I wander off, as old folks tend to do and always get a Hopper. Big Planning THANKS!!!
