You’ll have to give Venice another go. I’ve been twice- the first time with my eldest daughter, my sister and niece. My niece sussed out the cheap eats the first time and I took my youngest daughter back to the same places 3 years later. Stay away from St Marks Square for cheap eats. So saying, my time in Venice was the most expensive both trips because I went crazy in Murano! I haven’t been to Zagreb. It was on the itinerary for 2019-20 but we travelled round Andalusia, Spain for a month instead.
