The Silversea experience has been deliberately and systematically eroded by the management. By penny pinching, profit taking and metric splicing, the Royal people have eliminated the little and big touches that made Silversea seem special, and a luxury line. The product has been dumbed down so much.
Relaxing the dress code may make the pax look less elegant, but the Silversea bears the brunt of the blame for what has happened. Frankly, I do not think the management cares. The older and wiser Silversea pax of old are not valued, after all they are expendable just by virtue of age.
