I would take a step back and look at at the main functions of a hotel and create subheadings to work from, this will focus the search for a newbie a little, eg
Hotel itself
Hotel name, location, phone numbers, companies house reg details, email address, website details,outside adverts and agents
Resevations and reception
Resevation system, number of rooms, pricing of rooms, room details, rooms maintenance, rooms on/offline, Rev par per room, room specs, opening times, room facilities
Food and beverage
Menus, suppliers, food cost %, resevations,opening times, food hygiene details, pest control records, uniforms, changing rooms, special offers, booking system, complaints procedure, inventory of goods, stock control
Housekeeping
Laundry inventry, dry cleaning service, staffing requirements, equipment, maintenance
etc etc
The lists are endless so it helps to break out the hotel disiplines, hope this helps
