Has anyone used the Vaporetto dell'Arte in Venice? I have read good things about it such as it's never crowded like the regular vaporettos and it's clean and air conditioned, etc. I'm interested in using it to ride along the Grand Canal so I can take pictures but I'm wondering if it's possible to stand at the front of the vaporetto and take pictures and/or if the windows open for picture taking purposes. Can anyone advise? Thanks.
