# Change the dates of a reservation

> How to modify the check-in and check-out of a reservation, what happens with reservations from OTAs, and what to do when the system won't let you modify it.

## Before changing the dates

Before modifying a reservation, check two things:

<Steps>
  <Step title="There's real availability in the planning for the new dates">
    If there's no free room of the matching type for the new dates, the system won't allow the change. You can see this directly in the PMS planning.
  </Step>

  <Step title="The reservation isn't from an OTA">
    Reservations from external channels (Booking.com, Expedia, Hotelbeds, etc.) can't be modified in Roomdoo. Any change is made in the OTA itself and then syncs automatically into Roomdoo. More on this below in [Locked reservations](#when-the-reservation-is-locked).
  </Step>
</Steps>

## How to change the dates

<Steps>
  <Step title="Open the reservation">
    Click the reservation in the planning. You can also use the search bar in the top-right corner and find it by booking reference or guest name.
  </Step>

  <Step title="Reservation tab">
    Once inside the detail, go to the **Reservation** tab (the first one).
  </Step>

  <Step title="Change dates button">
    In the reservation details section, on the right, you'll find the **Change dates** button. If there's a padlock icon next to it, the reservation is locked (see the next section).
  </Step>

  <Step title="Pick the new dates">
    A pop-up opens with two calendars: one for the new check-in and one for the new check-out. Roomdoo shows the real availability for each day.
  </Step>

  <Step title="Review the price">
    You can adjust the price for the nights (by the rate, a fixed price per night, or per-day prices). The recalculated total appears at the bottom.
  </Step>

  <Step title="Save">
    Confirm, and the reservation is updated. The planning refreshes automatically.
  </Step>
</Steps>

## When the reservation is locked

If after clicking **Change dates** you see a message saying **"Reservation locked — these dates can't be modified"**, it almost always means the reservation came from an OTA.

Roomdoo locks modifications on these reservations automatically, so the change in the PMS and the change in the OTA don't get out of sync.

### How to know which channel the reservation came from

Inside the reservation, in the **Reservation → Details** tab, there's a field called **Sales channel** that shows where it came from (Booking.com, Expedia, direct website, etc.).

### What to do

<Steps>
  <Step title="Identify the OTA">
    Look at the sales channel in the reservation file.
  </Step>

  <Step title="Make the change from the OTA">
    Go into the corresponding OTA panel and change the dates there.
  </Step>

  <Step title="Wait for it to sync back to Roomdoo">
    As soon as the OTA confirms the change, it syncs to Roomdoo automatically. It usually takes seconds to a few minutes.
  </Step>
</Steps>

<Note>
  The system message only says "Reservation locked" without further detail. If the user sees this, it's most likely an OTA reservation — check the sales channel to confirm and guide them to the right channel.
</Note>

## Common cases

<AccordionGroup>
  <Accordion title="The system says no availability, but the planning shows free rooms">
    Possible causes:

    * **The room type isn't the same.** You're looking at free rooms of a different type than the one in the reservation. Availability is checked by room type, not globally.
    * **Free rooms have a restriction applied** (minimum stay, sales stop, channel restriction). A room can be physically free but not on sale for that specific date.
    * **There's a Wubook configuration issue** (mapping between Roomdoo room types and Wubook room types). If the mapping is incomplete, the system may report no availability even when there is. This needs technical help — [contact support](#when-to-contact-support).
  </Accordion>

  <Accordion title="It shows 'Reservation locked' but the reservation is direct, not from an OTA">
    If the reservation didn't come from an OTA but is still locked, there's probably a special flag applied (for example, a reservation created via an external integration that left the lock on).

    In that case, [contact support](#when-to-contact-support) with the booking reference — we'll review it.
  </Accordion>

  <Accordion title="It shows 'Something went wrong' when I try to save the change">
    This is a generic message that appears when Roomdoo rejects the change at the final step (on save), not when it blocks the modification from the start. The usual causes are:

    * **The reservation already has an issued invoice** and the change would affect billing
    * **There are attached services** that aren't standard (not a breakfast or a flexible extra) and don't allow date reassignment
    * **A conflict with another reservation** that landed in the new dates right before you saved
    * **A temporary database connection issue**

    Try again. If it persists, [contact support](#when-to-contact-support) with the booking reference.
  </Accordion>

  <Accordion title="The reservation doesn't appear when I search for it">
    If searching by booking reference or guest name doesn't return the reservation, first check that your filters are correct (no date filters in the way, on the right property).

    If it still doesn't show up, it could be:

    * The reservation is **cancelled** and your filters hide them by default
    * The reference you have is the OTA's, not Roomdoo's
    * The reservation hasn't arrived from the OTA yet (wait a few minutes and search again)

    After checking the above, if it still doesn't appear, [contact support](#when-to-contact-support).
  </Accordion>
</AccordionGroup>

## When to contact support

Contact support when:

* The **Invoicing** tab shows an invoice number with a series already issued (not the text "to invoice")
* The **Services** tab has a service that isn't a breakfast or a flexible standard extra
* The reservation **can't be found** and you've checked the usual filters
* "Reservation locked" appears on a reservation that **didn't come from an OTA**
* After several attempts, the generic **"Something went wrong"** keeps appearing

<Warning>
  Don't try to "duplicate" the reservation or create a new one with the dates you wanted as a workaround. If there's an issued invoice or complex services in play, doing so leaves accounting fragments that won't reconcile. Better to ask support to modify the original one safely.
</Warning>
