Does the elevator in the All Seasons Hotel require a credit card?

Yes.

All Seasons Hotel elevators are equipped with a card swiping system, mainly to reduce the entry of non-resident guests and other idle personnel into the guest room area and ensure the safety of hotel guests. Through a swipe card system, only hotel guests with a valid room access card or authorization can use the elevator to access a specific floor. This can effectively limit the intrusion of private space by outsiders and provide a safer and more comfortable environment for hotel customers.
