The cruise is nice and worthy. The bazaar is a must. But, you don't need to book a tour for them. There is no extra for paying a tour. Both are reachable by taxi or tram and you can do them on your own.
Very inexperienced guide, didn't know much info. She was rushing for time and wanted to stay just a couple hours after we have driven for 4h. After insisting, we left 5.30 but missed the most beautiful, the sunset. Lunch was not good at all. Big buffet, no flavor. The place is amazing but would find another way to go.
