I have been to Venice twice, both times all too fleetingly.
The first time was a day trip when we were on holiday in Croatia in 2006, then we returned in 2011 as part of a Mediterranean cruise. This gave us more time and, as it was an overnight stop, we got to see Venice by night.
On both occasion we spent the whole time running around like loons trying to see everything and photograph everything.
We really must go back some time and actually experience Venice properly: spend time to appreciate the sights, visit the museums and galleries, and re-mortgage the house for a coffee in St Mark’s Square.
