Actually I think the though process was more like this:
Ok, we have to deal with the monorail maintenance we have been putting off. We are at the point where it is increasingly dangerous to operate the monorails as they are and we have to get in front of the issue. So, do we just close down the entire monorail system for <insert time here, probably around a year> and rely solely on buses and watercraft or find a way to increase the time when the tracks are free of trains so we can work on the maintenance issues one at a time?
Well, I think the later is the better option. There will be some guests who get their panties all in a wad over the decision but in reality the majority will either not know this isn't the normal policy or get over it when they realize we will increase the frequency of buses to the effected resorts and add a monorail loop bus for those who need to get from resort to resort along the line.
Now, we will have to add a disclaimer to the marketing literature for the monorail resorts indicating that while the monorail will be running for the vast majority of the time the parks are open there will be periods of time when that is not the case but we have made alternate travel available for them so they don't have to worry about finding their own alternative.
In the end I don't for see this negatively effecting our bottom line all that much while a guest death due to the monorail's current condition would. Seems like a no-brainer to me.
Make it so number two.
