Ever since HotelClub joined Hotels.com, it has become increasingly difficult to find promo codes that worked with Singapore properties. While I generally do not use OTAs for hotel reservations since the nights do not count towards the loyalty programs that I am interested in, I still use them from time to time if the property I am interested in is a boutique one that does not belong to any major chain. In fact, OTAs like Kaligo which offers 10 bonus miles per S$1 spent on hotels are perfect for clocking up miles for business class flight redemptions.
