Wife and I fly into VIE from the US and have a 6.5 hour layover before our flight to Milan. We land at 8:30 AM and thought would be nice to get outside a bit to start acclimating to the time change. Not looking for anything fancy to do, but hoping for some suggestions. WIll just have our carry on bags so hoping to leave those at airport if we venture out (we are flying business class on Austrian Airlines, so maybe can leave in the lounge?). Thanks for your thoughts/suggestions!
