And.... as per the CSR official thread (which is very informative), it says.
Room locations:
Cabanas 9B is now Club Service for convention guests. When there is no convention being held at the CSR or the convention does not offer Club Level rooms, the rooms in Cabanas 9B are available to regular resort guests (however, they do not receive Club Level services).
So it is only available to convention guests, who would all be adults, so no children would be allowed access.
