# Manage Booking Manifest (/how-to/bookings/manage-booking-manifest)



The booking manifest tracks how many participants are attending and their demographic breakdown. Demographics are categories like "Adults", "Children", "Seniors", or any custom demographic defined on your activity. The manifest is used for capacity planning, reporting, and waiver tracking.

Viewing the manifest [#viewing-the-manifest]

1. Go to **Bookings** and open the booking.
2. On the **Overview** tab, the demographics section shows the current manifest.

Each demographic entry shows:

| Field     | Description                                                       |
| --------- | ----------------------------------------------------------------- |
| **Name**  | The demographic category (e.g., "Adults", "Children", "Infants"). |
| **Value** | The number of participants in this category.                      |

The **Total Participants** count is the sum of all demographic values.

Updating the manifest [#updating-the-manifest]

1. Go to **Bookings** and open the booking.
2. On the **Overview** tab, locate the demographics section.
3. Update the count for each demographic category.
4. Click **Save Manifest** (or the save action on the demographics section).

The request sends a list of demographics, each with:

| Field                | Description                                                                                             |
| -------------------- | ------------------------------------------------------------------------------------------------------- |
| **Demographic UUID** | The unique identifier of the demographic category (linked to the activity's demographic configuration). |
| **Name**             | The display name of the demographic.                                                                    |
| **Value**            | The updated participant count for this category.                                                        |

When to update the manifest [#when-to-update-the-manifest]

* **Walk-in additions**: A group shows up with more people than originally booked.
* **Party size changes**: The customer calls to add or remove participants.
* **Day-of adjustments**: Correct the count before check-in to ensure waiver tracking is accurate.
* **Reporting accuracy**: Ensure the participant counts reflect reality for end-of-day reports.

How demographics are set initially [#how-demographics-are-set-initially]

When a booking is created through the customer checkout flow, the customer selects their party size and demographics during the booking process. When a booking is [created from the dashboard](/how-to/bookings/create-a-booking), the demographics are based on the equipment selections and their default occupancy values.

Tips [#tips]

* **Demographics affect capacity calculations.** The scheduling engine uses total participants to check against equipment capacity limits. Increasing the manifest beyond equipment capacity may cause issues for future rescheduling operations.
* **Manifest changes do not affect pricing.** Updating demographics does not recalculate the booking's price. If your pricing is per-person, adjust the booking balance manually or add a [custom line item](/how-to/bookings/manage-line-items) for the additional guests.
* **Waivers are tied to the manifest.** If your activity requires waivers, the waiver tracking system uses the manifest count to determine how many waivers are needed. Update the manifest before check-in so the waiver count is accurate.
* **Demographics come from the activity configuration.** The available demographic categories (Adults, Children, etc.) are defined in the activity's settings. You cannot add new demographic categories from the booking -- only adjust the counts for existing ones.
