Venice is Venice. Nothing quite like it anywhere else and it should be on everyone’s bucket list. The problem with it being on everyone’s list is that it can be terribly crowded, and there isn’t a lot of room on some of those streets. Or I guess they aren’t streets but actually sidewalks and promenades.
If you go there, try to go when it is off-season, or as much off-season as Venice gets. Summer months, vacations times, school breaks and long weekends, check the calendar well before you make those reservations. We were there in early October and it was still crowded, but doable. We kept away from the main fairways as much as possible but even then, all we could think was, wow, if this is October, what is August like?
