Accor's favourite sale is back with up to 50% off all participating hotels worldwide. All you have to do is to book before 14 January 2016 with your Le Club Accorhotels membership number (free to join!) and you will be able to enjoy massive savings. I took advantage of this sale last year and ended up with some really cheap (and good) hotels in Sydney and Auckland (and earned Accor Gold in the process)!
