As stated the diversion might trip you up. Usually it will take you through a restricted area, CTA step or similar. The trick will be to find exactly where you are on the map when the diversion is thrown at you, look at where you are going to go for the diversion, then check the map and airspace etc. You might need to call centre for example to check the status of the airspace, even if you have it in your Notams. You may not even actually end up going there, they will just be looking to confirm that you are following the right steps first.
