I finally booked this for 3 nights for 270 euros. I was really tempted by the spa room at the park hyatt but I think this will be a better choice for first time visit. I will have diamond status when I check in and if hilton has a 2x/3x promo, this will work out beautifully.

I have spent enough time deciding the hotel but I'd rather spend more time researching Istanbul. Are there any activities that need to be booked far in advance? I have read about the popular sights like blue mosque, hagia sofia, topkapi palace, basilica cistern. We will definitely do the Culinary walk as well.
