when we are in venice the biennale art festival will be there. I know they have a web site but i can not make heads or tales of it because of the way it is organized.. Has anyone been there during the festival? we will not have a ton of time to take part in the festival but I thought maybe doing something at night or an hour or two one afternoon. Do we need advanced tickets for everything? I would love to see a listing of all events but i couldn't figure out a way to do that. (we will be there july first and second) thanks in advance.
