Walk in the enviroments!
I'm not saying a whole planet or any thing like that, but it would be nice depending on the environment you choose for your home that you are currently in, there would be an elevator/ door that would take you to a common area themed to your Background.
A Space Station with a huge observatory for the space environment,
A high tech mall for the for the futuristic city environment,
A valley of flowers with a small town with the mountain environment
Access to the docks and ships for the Docks environment.
You could add a few activities people could do in these environments. People could earn credits for example for spending time in VR games and get a ticket for: A space walk, A boat ride, riding horses, or drive a hover car depending on the background they are in. They could access these activities by going to the common areas and do these things with others who also have tickets. You could also add a theater to each environments common area that plays public domain movies. This would be a great opportunity for people to make friends to hang out later in the rooms.

I would be happy just being able to move around - some of the home environments are so cool looking!
