Graphics are pretty nice! But when I am trying to navigate with the first guy when he is asking for a room, after some time I receive this error:

FATAL ERROR in
action number 1
of Draw Event
for object obj_Hotel_Master:

Unable to find any instance for object index '100182' name '<undefined>'
at gml_Object_obj_Hotel_Master_Draw_0
############################################################################################
--------------------------------------------------------------------------------------------
stack frame is
gml_Object_obj_Hotel_Master_Draw_0 (line -1)

Happens when I have open the room choosing tab while the timer on a person runs out.

This game has a really good atmosphere. I think it would be even better if the map was a little smaller. This would make it easier to see the rooms without having to keep moving and coming back all the time.
