If you are being paid and your company has been fair to you then I think you should abide by you bosses request.
As it gets down the the final days I just disagree with your boss. You just gone one day without them being able to say good bye will cause more disruption.
On the last week approach your boss again. Tell her you have no intentions of saying anything bad about the company nor disclosing where you are going.
Let's say you had requested to your boss that you did not wish to have your leaving disclosed. Would you feel it would be fair for them to ignore your request?
