What a SUITE anniversary present!
As was posted, you must call the CRO/WDTC/TA to book Tower Club Level rooms and suites. Tower Club level rooms aren't a requested location, they have to be booked to guarantee you'll be on that floor. Non-DVC suites that are on Club Level floors, aren't bookable online.
The 14th floor is called the Tower Club Level, however, on your confirmation, it may read "STANDARD CLUB LEVEL," whereas an Atrium CLub level room will read, "ATRIUM CLUB LEVEL." If your reservation states "Atrium Club," then you have booked the 12th floor, which does not have any suites. You will need to book the 14th floor Tower Club level if you want to book a suite. There is also a one bedroom suite in the Garden Wing. This suite can be booked online because it isn't located on a Club Level floor, though it does come with full CL access.
There are 11 suites on the Tower Club Level and there are also 5 non-suite rooms. Of the 5 non-suite rooms, 2 are King rooms, both with TPV and 3 are Queen rooms: 1 BLV, 1 TPV and one HA. On average, the Tower Club non-suite rooms cost a bit less than $50 more per night Vs. an Atrium Club room.
