My hubby booked a weekend away at the Sebel, and bought me a day spa voucher for Villa Thalgo. The day spa is beautiful! As soon as you walk in you just turn off and start relaxing. I choose the 90min body wrap, which I highly recommend. Staff are great, and I really loved the before and after treatment time, where your invited to have a drink or tea, and your not rushed in or out. They even have a locker room to keep your belongings, and where you can robe up!

Approximate cost: $200

Best day spa in NSW!!
They have a pool, spa, steam room, showers and personal lockers which are all free to use when you book for any treatment. Even waxing!! Oh the also provide an assortment of herbal teas, coffee, juice and cookies.
My mother and I are regulars at this day spa. Make sure the day you go you arrive early and take your swimmers, to get the full experience. I normally arrive around 10am and stay till 5pm :)

Approximate cost: $100 for a massage
