Providing space on terrace

Dear Freinds,

We are a hotel and primarily registered under Mandapkeeper services.  However we have also provided space on terrace to Mobile vendors.  We sincerly feel that these services do not fall under the category of Renting of immovable property. 

Further according to us it shall also not fall under the category of sale of space as it does not pertain to display or advertisnment.

Request experts to let us know in which chargeable category to include the following services.
