yes, you can turn it off, but you have to edit a php file (the single room file, and remove a line of code, but we can help you), or you don’t use the rooms post type.
Also, could I use Ken Burns slider in homepage instead of the one you have on there now?
Yes, but I think you have to edit the header.php file and place your shortcode there. But normally it’s very easy.
On Mojo it’s a “lighter” version, in the version from our website there are much more shortcodes, options, settings and widgets.
