The new PORT system on these elevators has sure enough disappointed many fans of the former Miconic 10 feature. However, it is understandable why the Miconic 10 system was replaced as it often tended to glitch when being used, while the PORT system appears to have improven it.
Holding or repeatedly pushing the "Close Door" button is an abuse of the equipment and should be prosecuted by the hotel. This hotel still does not have enough security to keep the children who want to play on the elevators out. That's why I don't stay there anymore.
