WeTravel does not have a reinstate booking button but you can sign up your client again with this simple process. You will just have to use a workaround involving the "Add Participant" function.
1. First, go back to the trip builder and create a discount code under the Settings section for the exact amount per person your client has already paid, click Save and then Publish the trip to save it.
2. Go to "Trips" and click "Manage Trip".
3. Click on "Add Participant" to sign your client up again.
4. Choose the number of packages, apply the discount code, and click "Continue".
5. You will now have to enter participant information. You can use the information from the canceled booking. Once the information is filled in, please click on Continue.
6. Choose the add-on options. Note that this step will only appear if the trip has add-on options available.
7. Here, choose "No payment made yet" and click on "Confirm Booking". If a payment plan has been set up they will be automatically enrolled. More info on the "Add Participant" function here.
Once confirmed, you will see the following message: "Participant successfully added". The balance due should be correct thanks to the discount code that you used. If there are any discrepancies in the balance due, please feel free to use the Custom Price function to make any corrections.
