Unity Networking - Hosting multiple scenes simultaneously

Hey guys,

I really need advice on how to set this up in Unity. I can't seem to find any good resources on this.

What I want to achieve:

I need to have different independent "dungeons" hosted on a server. Players need to be able to switch between them. The host is a player as well. Now, how would I go about setting this up?

The approach I came up with:

On the server, load every dungeon into one scene (layed out so that they won't affect each other) and set the scope of the created objects so that they will only be synchronized with players in that dungeon.
On the client, load one dungeon at a time and reload the scene with another dungeon when the player switches dungeons.

Would that be a feasible approach? If not, how would you go about doing this?

I'm grateful for any thoughts on this.
