The short answer is 'yes'! The more you see and do using your Pass, the more you save.
But even if you only do a few things during your time in Istanbul, you will absolutely save money with Istanbul Tourist Pass. For example, if you were to book the Big Bus tour for 1 day (€45 per adult) and visit the two most popular museums in Istanbul, Hagia Sophia (€15 entry) and Topkapi Palace (€15 entry), and then at night do the Bosphorus Dinner Cruise with Shows (€50 per adult), these 4 activities in 1 day would already total €115. Meanwhile, our 2 day Istanbul Tourist Pass is only €95 and includes access to 35+ attractions, experiences and services!
That means you could hop-off the Big Bus at more places and get guided tours of Dolmabahce Palace, Basilica Cistern, Turkish and Islamic Arts Museum and the Blue Mosque, see the Whirling Dervishes, go shopping at the Grand Bazaar, use the airport shuttle bus and much more all for €95.
The only additional costs are for the one-way airport transfer (you get access to a special discounted price with Istanbul Tourist Pass) and a €0.50 security deposit for the wireless Internet hotspot, if you choose to use these.
