If you really want to go to Venice than do it, stay on the board walk and check out all the shops, almost all of them stay open year round and it's alot of fun to just go look at every thing. I dont think your going to see many if any of the street perfomers but I'm sure there will be a few die hards that still need to make a buck or two. I would'nt worry about getting hassled by anyone, just go have a good time.
