You can customise every single word on your online booking.
Meaning if you are only using English you can modify the words to your style.
Similarly, if you are using multi-language features then you can customise each language.
But it is not just on the online booking itself - the customisation extends to the communication (e.g. via email) and printing you have with your customers. This can also be customised. See below.

which results in the following changes in the printed (or emailed) documents
