Booking a sequence of events
Being able to book a number of events in one go

I see this as a bit of a "Composite Service", so a service that is defined as being composed of a proscribed series of other service offerings.
For example, a salon might have define "Manicure" and "Pedicure" and "Massage" services. Then they might want a bundle package service that combines all three: "Massage, Pedicure, Manicure". Booking this would require three consecutive timeslots, each of which could potentially be staffed independently.
