I read this in the late 1970s, but have long since lost the comic.
The villain in the story is a Walt Disney expy (short for "exported character"), and the story takes place at a serial-numbers-filed-off version of Disney World, with Micky/Minnie Mouse expy minions.
"Walt Disney" is using "Disney World" to harvest people's life energy to unnaturally preserve his life; their drained corpses are disposed of in various disaster "rides" and they are replaced with robots. I recall one of the rides has a bunch of people getting incinerated in a lava flow. (Maybe a Mt. Vesuvius ride.)
"Walt Disney" tries to trap Wonder Woman to use her life energy as a better battery than normal people, but the good guys defeat him.
As I recall the minions had "guns" that looked something like gumball machines.
