Great way to see all the highlights of both sides of the falls. Our tour guide was David and he was great. Pace was just right, not to rushed and not too slow. This was in the 'shoulder' season, September, so our group was not full capacity , just about right at around 25 in the group. Since the pickup was at our hotel, we did not have to negotiate any traffic or parking (it was a busy Saturday). Zipped through customs both ways. TIP: If you are so inclined to tip at the customary rate, be sure to bring enough cash, because most people these days don't carry a lot f cash and there is no cashless way to tip your guide.
