We were a group of four adults and two infants on our trip. Overall, it was a pleasant tour, though we felt it didn't quite justify the cost. The main attractions included were the Maid of the Mist and Cave of the Winds, with additional excursions priced at $2-3 each, but we were charged double.
Visiting Niagara Falls on weekdays allows you to avoid these inflated costs by purchasing tickets directly at the venues with shorter queues.
While we didn't have to wait in line to buy tickets, there were queues for the excursions themselves.
One highlight of the trip was our tour guide, Rob, who made the experience enjoyable despite these drawbacks.
