I'd been searching for Mantra discounts. They seem to have their pricing pretty well tied up, as their room rates when booking direct or via hotels.com & all the other online booking sites all appeared to be the same rate.
You can join their free membership program "Club.CuSoon". This provides a 5% guaranteed discount when you book via the Mantra website. Trawling the internet I found the attached coupon code for 10% discount. This worked for me for a domestic Mantra booking that I just made today. It has to be done via the Mantra website and you can't combine the 10% with the Club.CuSoon 5% discount. Don't know when the expiry is on this coupon code, so don't hang around.
By the way when go thru the booking process on the Mantra website, you can select payment via POLi if you have internet banking. This saves the 2% credit card fee. All up 12% discount :-D
Hope it saves you…………………
If you buy an Entertainment Book you will have access to www.departurelounge.com.au, where you can book cheaper rates for Mantra and Peppers resorts. Usually you have to book at least a month in advance and peak periods are often blocked out.
