Command and execution state

I have the folowing opertaion. I need to create a reservation, during the create of reservation I need to orchestrate several things. The reservation is ordered through a third party system, then an e-mail is sent , then a price offer is finalized and so on...

Can I encapuslate this logic in a single CreateReservationCommand or I need to have three commands and then what pattern would orchestrate the command execution ? Can a command has execution state at all ?
