Serious security failure!
In the middle of the night, an unknown man entered my room using a hotel-issued key card. He told me that the front desk had assigned him the room and provided him with the key. There were three front desk staff members on duty that night, yet none of them appeared to take the situation seriously or provide the support, reassurance, or explanation I needed. There was no manager on duty available to respond or follow up with me throughout my entire stay. This was not the level of service or hospitality I expected from a Marriott property.
