Home page contains all the widgets. How do I hide some or configure texts or change order like I was able to do in previous versions of the theme?

The homepage is now widgetized. As such, you can go to Admin > Appearance > Widgets and add any widgets to the Home Content Widget Area. This includes the new search widget as well as the accommodations, tour, cruise, car rental list widget each of which contains filters and configuration settings to adjust things to your needs.
