For the hydrotherapy pool experience, we were given disposable swimwear before we relaxed in these outdoor tubs. The idea behind this is that you go from hot to cold pools to relieve body aches (you will likely have this from the long plane ride!) and detoxing (which also helps with postflight puffiness). We spent 20 minutes in a hot bubbly tub set at around 37 degrees Celsius (to soothe) before moving onto a cooler one set around 32 degrees Celsius (for a stimulating effect). While we were mostly left alone, someone from the spa came by to tell us when to switch tubs.
