The walk from BWV takes less time than a boat ride. In all, it's about 8-10 minutes to the International Gateway entrance. If you are right at the Boardwalk dock when a boat is about to leave, it may be a tossup. Otherwise, the walk is quicker. The only time I would opt for the boat is if it is raining or excruciatingly hot. Then. the boat would offer shelter and air conditioning.....
