Would it not be just as easy, since you have to do it anyway, create a seperate voom-out movie clip for each floor/room. Then set the button with a GoToand Play function for that movie selecting a specific frame set? Example. You are in scene one within room one (stop function on say frame 125), you then have the voom-out clip on frames 135, 145, and 155. The viewer clicks on button 2 and the movie jumps to frame 135 and plays the voom-out then loads scene 2 for rooom 2. If they clicked on button 3 the movie would jump to frame 145 and zoom out and load scene 3 for room 3. Does that make sense?

I think that would do what you want without a lot of scripting.
