Forums and making different calculations

I wonder if I bought a travel agency theme and you got a possibility or an option to make prices prices calculate passed on number of travellers ( it can’t be the same for 5 people for example because they will be using bigger car) in addition can I have a possibility to make choice of services for the same product and make my guest pic from them for the same tour . I.e. 5 days trip in X destination and guest need to choose between 3/4/5 star hotel before making a purchase and buy the tour?
