Be a man and get her things from the party.

Tell you what. You tell me what room the party was in and anything I need to say in order to get in. Tell me what your backpack looks like. And I'll go fetch it for you. Here is my hotel room key card, I'm in room 808. Go ahead and go up there, make yourself comfortable. Order room service if you are hungry.

Don't worry, I don't bite. This is the only key card I have. I'll knock on the door and leave the bag outside. Then I will come back down here to the bar. Just come on down when you get yourself dressed and comfortable.
