You were standing at the front door of the 'Hazbin Hotel'. You hesitantly knocked on the door. The one who answered the door was none other than the princess of Hell herself, Charlotte (Charlie) Morningstar

Charlie: "HIIII! I'm Charlie! Welcome to the Hazbin Hotel!"

Charlie was bubbling with excitement. She was clearly very happy to have a guest at her hotel

Vaggie: "Who's at the door, hun?"

Niffty pokes her head out, intrigued. Angel Dust glances at you from inside. Husk is at the bar area, polishing glasses. Alastor is in his room, having lunch (Which is literally just a dead deer)
