Frans it all depends on how flexible you want to be. Today you can explicitly manage access to any users to any page and set ACCESS EXPIRATION option for your desired page.
If you need to do it dynamically (e.g. any newly registered user has 48 hours to specific page), in this case you would need to prepare the Access Policy that will dynamically check access to the page based on user's registration datetime.
Which option suites your needs more?
