The Ice Palace machines are most certainly NOT in mint condition. They're pretty promptly repaired if something catastrophic happens (the Lethal Weapon 3, for instance, had foreign objects crammed in both of its coin slots), but they are not nearly as flawless as those descriptions make them out to be, and comparatively small things like the kickback on Gilligan's Island not working have remained broken for years.
Then again, maybe that's because I stick notes onto the machines themselves if I encounter something wrong with them.
It is not nearly as bad as Family Amusement Corporation, however. Stuff like the Ace in the Hole scoop in World Poker Tour and the vault in Sopranos needing a VERY strong hit to detect have been that way ever since I started visiting the place, though in that case, they don't seem to have a dedicated and knowledgeable pinball repair person, but instead the general maintenance person tries his best to understand what's wrong. They don't do any whitewashing of descriptions though. I'm not sure if they know they're on Pinball Map.
I'll be visiting AYCE Gogi sometime very soon too; I want confirmation in person if the America's Most Haunted is actually there. Bear in mind that the machines are not turned on during weekday afternoons. I'll ask someone there if they can be turned on upon request, as I intend to go during lunch hours.
