I signed up for the $5 credit last week on this website, don't think I will use it on this deal but i though I would post this for others to see. It doesn't seem like a bad deal for a self contained apartment.
Voucher can be used until 23 December 2012, not valid for use over the Easter or September/October Holidays. Does not say anything about the June holidays so i guess those dates are not blocked out.
Can have more guests at extra cost.
I would be interested to hear if anyone has stayed here before (rated 3.5 stars), it seems like a reasonable place to stay for a cheap family holiday if you want to get out and spend your money on the Gold Coast attractions rather than on accommodation.
