For the same sort of money you'd pay at Blue Marine you'd probably be better at Club Andaman which is also within walking distance of Patong shopping/restaurants and nightlife wheras the Blue Marine you would need a tuktuk every time. The gardens, pool area and bungalows and I think the ground floor have all been totally refurbished last 18 months....had to be as it all got trashed by the tsunami.
