[Membership 2 Pro] appointments + membership

I just started a trial for wpmudev.
I want to use appointments+ + membership2 to do this: I have 3 spa locations. I want to offer a custom dashboard and appointment system for each location. But I want the location manager to have access only to her services and providers, well and her appointments and the rest of her location appointment system.
I can to do this with one single appointment + membership installation or i need to do a multisite installation and offer separate appointment+membership for each location ??

Thanks for your help and sorry for my poor english.
