You will be having a set of guidelines giving the details of the service taxes as applicable and deductible at the rates as applicable for various services.
If the package covers the air travel, room booking and conveyance, then the service tax charged may be at uniform rate, but if you charge separately for each service, you may safely deduct the taxes as per provisions of law individually on the bills generated.
This depends on the practical situation, hence you may refer to previous deductions which my be available in the files for further guidance.
