What's the difference between a "reservation" and a "booking?" A Reservation consists of one or more Bookings. That's it.
Every booking belongs to a reservation. EMS lets you have multiple bookings under a single reservation. When you have multiple bookings in a reservation, each booking can be independent of the other, such as reserving a set of rooms for an event, or can be a series of bookings under a Recurring reservation.
Each booking can contain multiple Booking Details, which are the resources and services required to support the booking, such as catering and room setup.
A reservation is the "who and what" of an event. For example, the Academic Planning Board (the who) can reserve space for a Semester Kickoff event (the what).
Reservation Details displays detailed summary information (the Reservation ID, the Event Name, the Event Type, and so on) for the selected reservation and all its bookings as well as attendees and any services that were requested for the bookings.
A booking is the "where and when" of an event. For example, the Academic Planning Board schedules a conference room (the where) for a staff meeting on the second Monday in January (the when). The Academic Planning Board now has a single reservation with a single booking in EMS. If, however, they schedule the conference room (the where) for a staff meeting on the second Monday of each month for a year (the when), then the board now has a single reservation with 12 bookings.
A booking can have one or more booking details associated with it. Booking details are the resources (items for the meeting) or services (people and their activities) that are needed for an event, the notes for the event, the activities for the event, the room charges for the event, or any combination of these.
