I have joined and redeemed my vouchers at Westin Desaru Coast. I feel very worth to join. I saved a lot on my trip to Westin Desaru Coast for family of 5 adults 2 kids. Not only on accommodation but also dining. My sales rep is helpful and if you are interested to join can let me know. I can intro you a good sales rep. To book the hotel, you have to email to the service center, I usually get the response in a working day time (unless during long weekend/ public holidays).
