I've just booked myself arriving DOH early morning, flying out just after midnight - a stop of about 17 hours. Was hoping to do some sightseeing in Doha (and rest my head in a hotel briefly, thanks to QR). Alas this scenario is booked for a Friday... how closed/dead/uninteresting will Doha be on a Friday? My primary interest is food/society/markets and maybe a short excursion. Should I absolutely change the date?
