Saw this deal at Scoopon with vouchers still available for 4 people (for 2 they're sold out), so it's suitable for a family of 4 or 2 couples. You can choose to stay 2 or 3 nights, for $379 or $479 respectively, which is a discount of over 60% off prices you would get through other booking sites.
2 nights for a rustic 2 bedroom log cabin for 4 people, with spa or corner bath, kitchenette and balcony with Bellbird Valley views would cost you $379 with this Scoopon voucher vs. $864 you would have to pay through Booking.com, Trivago, Hotels.com, Expedia, Last Minute, etc.
Daily continental breakfast, 3 course meal for 2 people with a bottle of wine to share on your choice of evening is included with this voucher.
Voucher can be redeemed for stays until the 23rd of December 2016, but is not valid for long weekends and public holidays. Availability is limited over the weekends and NSW school holidays, so it's recommended to book in advance.
Plenty of things to do around the area including bushwalking, whitewater rafting, fishing, horseriding and mountain biking, plus there are lots of picnic and barbecue areas nearby.
