Final answer:
The hotel property can take control over the SNA benefit and guarantee a complimentary suite for a guest by having the rooms controller balance the system and decide who will receive a suite upgrade.
Step-by-step explanation:
The answer to the question is d) Yes, rooms controller can balance the system and decides who will receive a Suite upgrade.
This answer is based on the understanding that SNA benefit refers to Suite Night Awards, which are a type of benefit or perk given to elite members of a hotel loyalty program. The property or hotel management does have control over the SNA benefit and can decide who will receive a complimentary suite upgrade.
In this case, the rooms controller receives the request via the GXP (Guest Experience Platform) and has the authority to assign the suite upgrade to a guest based on factors such as availability and eligibility.
