If you get into the habit of vacating at the first available exit, then you won't have any trouble flying into busy airports. Part of the route to becoming a "Professional Pilot".
At busy airports the difference is noticeable between those that have and those that haven't acquired the skill of "vacating at the first available". The lesser professional pilots end up being the limiting factor in "runway capacity" and are the main cause of "holding". A fact that most airlines seem to oblivious to.
