You must go, as someone said get the water taxi (V) they mentioned you can get a special ticket so you can get on & off etc, it comes with a map. Must go to San Marc square & if you haven’t got time to visit museums ( long q’s) go in the shop (Bascilla)so you can look at the ceilings, gold to get the picture. In the square it’s surrounded with cafes they are expensive as is the gonderlas but if you walk about just outside they are cheaper. Don’t forget a cocktail in Harrys bar. Visit Murrano the glass island & visit the glass blowers in action, have a walk around & enjoy a snack by the water & a drink. Once you’ve been you’ll want to return.I’ll try & post a pic for you to get the picture. Enjoy the magic
