I'm posting this since quite a few people haven't been aware of the several features that non-members are allowed to use. So here's a few pointers.
Sanctuary is located in the Trinity Town Center near the trees in the middle of the area. You'll notice a portal around there; that's the entrance. Sanctuary is accessible to all players, members and non-members.
There is a key dispenser in one of the rooms close to the entrance. You can take a key if you want, it will allow you to port straight into sanctuary by using the portal stone. In the same room, you will notice that a banker will be there along with a persistent chest to store or take out your gear.
Many of the exact same stores in Trinity are located in Sanctuary as well, so take some time to explore a bit.
There is also a certain... Special PvP Arena called the Hall of Blood. Feel free to use it.
Finally, Grith (funny looking guy) will port you to certain special areas if you have the required journal entries.
Non-members have access to all of the above mentioned features. You are welcomed to use them.
If you guys have any questions, please PM me or ask in-game.
