An invitation from the queen is not an invitation, even if it may look like one.
Its a command to appear.
If that is so then the Queen can try to send her guards to prove that. But if she is asking for the party to appear then that is because she needs them to do something and being an annoying wench to a group of people who can generally level a small city when made angry is not a good way to accomplish that.
