We did the tour the day after Canada Day on a Sunday, so the ride took about 3 hrs instead of usual 1.5 hrs. The bus driver was great; however the tour guide wasn't really a guide so he didn't know much about the falls and worse still the AC on the bus didn't work and it was quite warm the day we went. It was quite crowded at the falls and when we got to there the guide didn't know how to get us to the boats. The boat to the falls was great but a bit crowded. Dinner in the Sheraton was worth it in that the food was tasty and we didn't have to worry about finding a place to eat.
