The concierge is a person who is there to help anyone is a GS or up and D+ (some ships have D as well). They have a lounge where drinks (you don't haver to pay for) are served during the cocktail hour each night. You will be given a key to access the concierge lounge and no one else is suppose to use it.
The concierge will help you with reservations for dining, reconfirming your flight (usually) and many other things be it problems or just needing help onboard the ship.
There is usually a light breakfast you can help yourself to each morning and an expresso or something like it machine that is available all day. There are also computers for your use. Supposedly gives you more privacy but really doesn't.
If you are going to entertain in your suite the concierge will usually help you with that too.
