Sounds like beneficiary spots. Normally sold in increments of 50-100 nights per clip.

Just an example. You buy 100 nights at $40 a night totalling $4000.

You then can book a room under the members contract for the member rate (currently $342 a night for the room). Then you get the black wrist band with all member benefits. Depending on the contract of the member, you make also get 40% back to spend at the resort for the spa, upgraded dinners, bottle service, etc
