I have a particular use case that I am trying to solve for, I didn't want to go custom and wanted to see if a contrib module exists that the community could point me to. I have a site locally only using D7
I have hotel Admins and Hotel Customers. I created terms in the vocabulary: Hotels (Hyatt, Holiday Inn, etc).
Hotel Admins are assigned a taxonomy term on user creation. I'm using Role Delegation to allow Hotel Admins to sign up Hotel Customers to use a service that the hotel offers.
