Set minimum persons per booking

#1

Hello

I am using the Adventure Tours theme from themeforest
I have a travel agency, we do one day tours, and the minimum number of participants for a new booking is 2. Is it possible to set the minimum numbers for a purchase to 2? And then add a message that will also say this in the booking box so the client understands

Please help me with this
