code to remove custom taxonomy metabox form custom post type hotel page

function my_remove_meta_boxes() {

add_action( 'admin_menu', 'my_remove_meta_boxes' );

Change register_taxonomy() : you have kept

'show_ui' => true,

change it to

'show_ui' => false,

this argument determines whether or not a user interface should be displayed to manage the taxonomy. As you don’t want it, you have to set it to false.
