I don’t know Venice, but the snook should have at least started schooling up on the gulf beaches by now. I’d try the outside of inlets there with a white grub or a bone spook jr. if no one gives you a particular spot. The fish will be right up against the beach if they’re there. I could help you if you are willing to drive a bit south of there, but it sounds like you are strapped for time as is.
Go in the canals look for large boats on docks that have a lighting system and drift bait with the tide past the hulls and see what comes out of the shadows.
