Just to make sure that you are standing in front of the supplies closet - when you arrive at the Sylvia Hotel, did you go forward three times, right, forward, and then left, and then try opening the door?

hi Marian, i cannot get in. robert.

Okay, I just wanted to make sure. Let's wait and see what MaG has to say.

Robert,

Can you please check all your inventory - scroll using the arrows from beginning to end.
See if you have the box and/or the hotel keys.
The keys should be automatically returned when you go to the factory but since you said you did not get the box - maybe you still have it.
Please keep us posted.
