Why not take a float?
I recently went to Saltuary in Five Dock to take photos of their incredibly relaxing sanctuary. A space where you can relax in the Himalayan Salt Room or take a float in the amazing float tanks (I loved that the ceiling of the float tank twinkled with stars and unlike other tanks it was a high ceiling more like a room than a small tank. You could have a massage or simply relax with a cup of tea while perusing the health store. I walked out of this place so mellow it was a dream.
