2. RatesToGo.com - up to 20% off Hotels
From now until 10 August 2014, take 20% off hotel stays when you book at RatesToGo.com with the promo code GETAWAY20. This is valid for stays up until 31 August 2014.
For stays after 31 August 2014, use GETAWAY15 for 15% off instead.
RatesToGo.com ran a couple of limited time promotions that offer 20% off hotels this year. However, with that being said, it's always a good idea to cross check with other OTAs like Zuji.com.sg or HotelTravel.com.sg to make sure you're getting the best rate that matches your preferences!
