No, I would not think so. While the parking lot next to the canal lockhouse is fairly small, if you drive through the tunnel under the canal, you will reach a very large parking lot on the river side of the canal. It has lots of capacity (at least 150 cars, I expect). It was nowhere close to full yesterday afternoon when I rode past. (Admittedly, that was a Sunday afternoon in August.).
