EDIT 3-12 CLOSED, LINK DEAD.
It's back again, hotelclub is like a revolving door of free credit! Just have to say which foxtel channel you saw this promotion on (but no proof asked). Crdit is US$50 which is good with the current exchange rate.
Don't seem to be able to use it with the previous 'hack' of $30 added credit for Christmas. But you can easily become a new customer just by choosing a new email address - I've got ?5 accounts now ;-), main problem is remembering which one has the credit!
A+
Anyone tried booking consecutive nights at a hotel under different accounts? Would it mean checking in and out every day?
