Hey, if your family will be traveling together in Istanbul they can share one card, they don't need to have one each.

İstanbul transport card for 3-8 of January
Anybody can borrow an istanbul transportation card or akbil for use between 3 and 8 of january? My family is coming for visit and buying 2 cards for just 5 days of use seems pretty senseless.
