If I am bugging out to a hotel or any reasonably stale urban environment, all I really need is important papers, prescription meds and cash/plastic.  
When we have had to prepare to bug out, my wife and I have found a check list to be most invaluable.  The first things on it are what I call the four Ps - people, pets, photos, and papers.  Perhaps we should throw in Prescriptions, as well.
