GST on Sale of event tickets

Hello,

Suppose XYZ Ltd. sells ticket for an event through online agent. The event ticket price includes Hotel accommodation fees. XYZ ltd. pays to hotel its accommodation fees. 

The question is whether the hotel accommodation fees would be included as outward supplies for XYZ ltd. or XYZ ltd. would be considered as pure agent for hotel accommodation part and other services would be taxed as outward supplies?
