Mixed Reality Acer with Unity

Options
So I'm trying to set up a simple scene in unity where different players can interact with each other online, a la VRChat.

I'm having a hard time implementing with this using MRTK and I was hoping I could get some help.

How can I follow a player model using an MR headset? Should I leave the MRTK scene components in each room I create, or should I child the Mr camera and all of its matching prefabs to each player so that when instantiated in a scene, they will each have their own MR camera?
Are there any reliable guides for using MR with photon?

I'd really appreciate the help, I'm very stumped at the moment.
