You’ll earn the equivalent of 4 Miles for every US dollar you spend. (Whatever currency you use it’ll be converted into its equivalent in US dollars.) And you’ll earn Miles on whatever you buy in your hotel – whether it’s a meal in the restaurant or a massage in the fitness centre. The offer is for stays between 28th June until 31st August 2008.
