I think I'd rather get a root canal than attempt fishing the canal during peak season. I'd rather see a fall run get together, where maybe it's an albie and bass opportunity on beaches south. I don't know what the regulations are or cost for an outing at either horse neck beach in Westport or the park at gooseberry point, but there is lots of fishy water on both sides and ample parking. The point is free parking and I would think a cook out is doable.
Outer Cape is a night time game now if you want to catch fish from shore. I'll be out there 6-20-7/2. Not great tides those days. You will be fishing with the souls of past legends out there though.
