Not an issue for me as I don't do a package, Jim, but your point is a good one. Folks need to be aware of the consequences of their actions and not blindly follow what any one person (like me) sez.
And personally, I'm not surprised that Disney will clamp down on last minute additions.
But I can still think of a legitimate way to get to the Fort that hasn't been discussed. We've covered theme park bus rides, Disney Springs bus rides, MK boat rides, and drive-up-to-the-door-of-the-Fort attempts. Like I said, if Disney is clamping down this hard, they probably already have covered the one option I'm thinking of and just not let THAT CAT out of the bag yet.

PS - and
@StormyCA, I had not considered the various possible "Seal Team 6" approaches to the Fort (you left out parachuting in during sleep time) but that's also a option, I suppose.
