Rooms vs Accommodation
If you are going to use the MotoPress Hotel Booking plugin, you'll want to use the Accommodation Custom Post Type (WP Dash / Accommodations / Accommodation Types) with the supporting Accommodation Grid Elementor Widget. Explained here: https://themovation.helpscoutdocs.com/category/225-hotel-booking
If you aren't going to use MotoPress Hotel Booking Plugin, then use Rooms Custom Post Type (WP Dash / Rooms) with the supporting Room Grid Elementor Widget.
We created two separate Custom Post Types because some people might want to use a custom booking system and not the bundled MotoPress booking plugin.
