While I have slight reservations about the "points-for-hotel-booking" sites like Kaligo, Rocketmiles etc (not least because of the lack of recognition of status during stays), there can be real value in their sign-up bonuses. One such option is currently available through Kaligo and Etihad Guest. You will get: 5,000 bonus miles when you spend $500 USD or more cumulatively by 31 March 2016; OR 10,000 bonus miles when you spend $1,000 USD or more cumulatively by 31 March 2016; OR 20,000 bonus miles when you spend $2,000 USD or more cumulatively by 31 March 2016 Full details are here.
