You can argue hypotheticals, but when it comes down to it the GM has stated that this location is secure.<br/><br/>If "This Prince seems be lax about security, and that's a crack in his armor that could be exploited" is a plot, then cool. But the GM has said that it is not. Continuing to push on it doesn't serve the game very well.<br/><br/>The Kennedy Center, in point of fact, is built like a fortress and is secure enough that Presidents go there relatively often for performances. It's also just a cool location. So setting the opening scene there makes sense. If we can suspend disbelief enough to roll with undead monsters getting together to have a party then we can accept this.<br/>
