Hi, Our first full day in Istanbul will be May 19th which is Attaturk Commemoration Day and Youth Day. Does anyone know if the local transport will be running on a different schedule from normal, will the major sights such as the archeological museum be closed that day? This is a Sunday so I know the Grand Bazaar won't be open and the Spice Market may or may not be open depending on the guidebook you read. I can't find the answers to these questions in my guidebooks. Thanks.
