I have always wanted to TAKE A SHOWER AT AN AIRPORT. At Dubai airport I finally did this at the Marhaba Lounge. Dubai Airport also has a complementary free but public shower.
In this video, I have shared my experience of the departures area of Terminal 3 of Dubai Airport while flying Emirates to India. The lounge access also comes for free with a Priority Pass (for some priority passes, there might be a small charge) and some other cards.
