If your trip has already started and you want to change the length of your home reservation, you can submit a change request to your host. However, there are a few things to bear in mind before you do:
Depending on the host’s policy, changes to the number of guests may affect the total cost of your stay. This will be automatically reflected in your bill once your host confirms the changes before you finalize.
If the request is declined, or you don’t receive a response from your host, your reservation will stay the same.
For a hotel stay, you’ll need to contact the hotel directly to change your reservation. Note that this may not be possible and would need to be authorized at the hotel’s sole discretion. Tip: Calling your hotel can lead to a quicker response.
