If ACF Post Object post has custom taxonomy term…

Instead of is_tax(), which

Determines whether the query is for an existing custom taxonomy
archive page.

you should use has_term(),

Check if the current post has any of given terms.

Like so,

if ( has_term( 'booked', 'room_vacancy', $post_object ) ) {
  // Yay!
}
