Venice is a beautiful city, but can be difficult to navigate, I found this in a previous thread
You can also take the Alilaguna Water shuttle.

Look on the map to see the route. It takes about one hour but it ist much nicer than to go by bus or taxi. Transportation by taxi: about 30 minutes.

Booking a shuttle like this would be mor relaxing, are you arriving the same day ?
