The page link field actually stores the post ID, which gets formatted internally by the get_field
function on output. The 3rd argument for get_field
lets you disable that output formatting so you just get the ID back, which you can then use to get title and permalink for that post:
$post_id = get_field( 'bookitall_roomstype', false, false );
if( $post_id ):
echo get_the_permalink( $post_id );
echo get_the_title( $post_id );
endif;
