RCM on import of service comes under RCM if, Taxable services provided or agreed to be provided by any person who is located in a non-taxable territory and received by any person located in the taxable territory other than non-assessee online recipient (OIDAR).
In you case service provider is located out of India. But another condition is received by a person located in taxable territory.
You are also located in taxable territory.
Now last point to check is Service are received in India or not.
To check this we need to refer to place of supply in case of import of services.
Referring to place of supply in case of imported services, tour operator services are attached to physical location and hence the location of physical place shall be considered for taxation purpose.
In your and in my opinion you do not have to charge tax under RCM.
Please refer Place of supply definition as per IGST Act, 2017.
