One correction to ohmark's post regarding the concierge lounges: They open Sunday evening (for appetizers and dessert) and close after breakfast on Fridays (usually at noon, although sometimes as early as 10 am).

The guarantee for concierge lounge access or a free continental breakfast at FS properties is backed up with cash. If you do not receive either at a FS property on a weekday, you can claim $100 at the front desk.
