Not sure a Venice novice could walk there that quickly. . .
(Rats! I was on my Kindle and it spell-checked me to the wrong there/their/they're!)

It is definitely walkable. However, the kilometric measurements don't take into consideration three major considerations in Venice: climbing bridges, stopping to gape at the beauty and take photographs, and getting lost.

You can fit ALL your items into the time you have--or not. We have no idea how slowly or quickly you will make your way through the sights you've mentioned. Some people can visit the Doge's Palace in an hour. Some need three. Prioritize your ist to be sure you actual get to see the places most important to you no matter the time you have.

I suggest you also get a good paper map, just in case.

Phone maps and GPS in Venice are problematic at best, as in so many places, one cannot get a decent horizon. Google maps are pretty hopeless, as Google has never been able to get a handle on the numbering system in each sestiere. Get a good paper map, not just a throw away one from your hotel. In terms of walking times, you are doing well if you can walk a kilometre in 15 minutes, and even slower on the Piazza / Rialto /. Accademia routes.

You will walk past the Church of San Stefano. It has a beautiful "ships keel" roof. The statue of a gentleman in Campo San Stefano is known by Venetians as el Cagalibri, or The Book Shitter. You can see why.

On your way to Ca' Rezzonico, you will pass the Snack Bar Toletta on your right. Good baguettes filled with cheese and meat, great value at 4 euro, and the bar Ai Artisti in Campo San Barnaba, near Ca' Rezzonico is good, with friendly staff. Have a look at the giant carp and turtles in the little fish pond at Ca' Rezzonico - those fish must be decades old.

I've written several trip reports for Venice. If you click on my user name, you would find them.

Maybe be a bit long and boring, not much useful info ....

The best street map of Venice is Streetwise Venice sold at Barnes/Noble.

@Peter_S_Aus your trip reports are amazing! I've cut and pasted large sections to plan my trip in Spring 2015. Thanks!

@LR220, I hope I'm not breaking any Fodor rules by asking if you might consider emailing me a copy of your trip spreadsheet. I am considering going to many of the places you are traveling to in March 2015. I will have 13 days (plus two travel days). The only thing set in stone is we are flying open jaw into Rome and out of Venice. If I've overstepped, I apologize. If not, my email is: [email protected]. Thanks so much! Hope you have an incredible trip!

if the queue for the campanile in San Marco is very long, you could get the vaporetto over to the island of san giorgio and climb the tower there - it's cheaper and the view is just as good.

do try to find time for just wandering around, perhaps in the evening when the trippers have gone home - it is one of the great pleasures of being in Venice.

Thank you all!

@ellenem, we'd definitely walk at a more leisurely pace in Venice, but I figured that if we were done with what we wanted to see at San Marco for the day, we could walk to Ca' Rezzonico before it closed. Though, it's hard to determine how long we would be spending at San Marco now, aside from the tours we are planning to take. It will also depend on other factors that can only be determined when actually there, but we wanted to try to plan for it just in case we do decide to go so that's why the distance, directions, etc were being sussed out.

Peter_S_Aus, I started reading one of your wonderful trip reports when I was organizing my itinerary for Verona. I will continue to do so to get some more ideas! Thank you for your suggestions!

Pepper_von_snoot, thank you!

mogsanova, I don't mind sending it to you, but it will take me a while to complete it (hopefully within the next month!), we have to finish our Milan and Rome itinerary, but we are also putting in some other information for aperitivi, dinners, etc. The places we are visiting in Italy are Milan (& Como) -> Verona -> Venice -> Florence -> Pisa -> Cinque Terre -> Rome.

annhig, thank you for the suggestion! We are going to be using the evenings to wander around Venice. I found out that there's a 20€ (+4) Rolling Venice Card that allows free vaporetto rides for 72 hours for youth. I can't seem to find any information regarding discounts (though I heard there is one for Doges Palace) and a lot of info seems to be outdated even going back 2-3 years.

"I found out that there's a 20€ (+4) Rolling Venice Card that allows free vaporetto rides for 72 hours for youth."

The Rolling Venice Card (4€) gives you discounts on many things, including the ability to purchase a 72-hour travel card for the vaporetti for 20€ instead of 35€. So if all you are interested in is the travel card, the 4€ investment in a Rolling Venice Card saves you 11€ immediately.

This might be a stupid question but for a gondola ride that charges 80€ - 100€, is it per person or would we be splitting that cost between two of us?

That is the total cost for up to six people in one gondola for 40 minutes.
