Here is some info I found...
What are the Concierge rooms like?
The Concierge Floors - 12 and 14 - have two types of rooms - standard and suites. The standard rooms are identical to the Tower rooms below, only with a larger balcony area. Standard rooms are available on the 12th floor only. The 14th floor has both standard and suite rooms.
There is a BIG difference in the concierge services between the two floors. The 12th floor is called the Tower Club, which is basically Contemporary Concierge Light. Concierge services are available from 7am to 4pm on the 12th floor. Special services on the 12th floor include: complimentary continental breakfast, and concierge services during 7-4pm.
Now, the 14th floor concierge is a full service concierge. There is a FULL continental breakfast (much bigger than the 12th floor), daily appetizers catered by the California Grill, and nightly desserts catered by the California Grill. There is a nightly turndown service, and they leave a little chocolate Mickey (solid chocolate) on your pillow every night. The concierge is available from 7am to 10pm to make dining reservations, plan outings, answer questions, everything.

The concierge lounge on the 14th floor ONLY has free beer, wine, soda, and bottled water all day. Each 14th floor level room has a refrigerator stocked with free soda and juice. Room rates are double the average tower room, so you can determine if the service is worth the added expense. Discounts are sometimes offered on the 12th floor rooms, such as Annual Passholder discounts. Discounts are rare for the 14th floor suite rooms.
