That's actually a pretty good analogy.

The man at the front door (the outer firewall) keeps the obvious crazies

The lobby (the DMZ) hosts the publicly-accessible services (restaurant,
bar, conference rooms, etc.)

The cardkey-locked door in the back (the inner firewall) lets
tenants/guests get to the rooms and pool.

Now you just have to worry about people climbing in the windows... :)
