Hello @arkiavimal,
Actually, the demo of the Wp Travel plugin is made using the Travel log theme and the layout of the trips on the front page is provided by the theme itself.
So if you want to display the trips as in the demo then you can consider using the Travel Log theme whose link is provided below:

But if you want the layout i.e. display dates in your existing theme then you can always consider hiring the professional developer so that your theme won’t be affected in any way.
To hire the developer please refer to below link:

Thank you 🙂 .
Best Regards!!!
Have a good day.
