[otrs] Unique Customer Base

Looking for recommendations on how to use OTRS most efficiently for our customer base. We offer services to hotels therefore we're looking for a way to do trouble ticketing by hotel and room. We have no need of First Name/Last Name for a customer. I thought about using Hotel Name, City for First Name, Last Name and the Account Number for the hotel as the ID but not sure where to integrate room numbers. Just installed the system for the first time so I'm trying to go through the documentation but was wondering if anyone had a similar setup or recommendations. Thanks R. Hayes
