Large numbers of hotels have concierge service rooms. Things noted above are included. They also come in and turn down your bed in the evening, you have your own lounge where you can get food (mostly quick stuff) and drinks, you have concierge check-in so you don't have to wait in line. you have at your call concierge CM's who will answer your questions, make reservations for you, get you a newspaper, carry you downstairs if you want (just kidding, but only almost, on that last one). You can also do the sunrise safari at AK (it costs extra but is open only to concierge guests). In other words, unlike the normal hotel guest, you get special treatment with special services devoted just to concierge level.
