Do you need a private green room?

Absolutely not, I've shared rooms with many dancers and other performers, it's just good to be able to have a somewhere to sit and go through the script beforehand

Can you make the script your own?

100%! I always recommend a client provides a script or script guide because they will know the event, brand and tone better than I to begin with, but I always bring my own personality and energy (if required) to the job in question.
