Darrell was great! I didn't know what to expect when I booked this tour, but we were paired with two couples (6 tourists total) in a nicely appointed Mercedes van and our guide, Darrell, talked us through Niagara and to our various stops. Although he did not accompany us during the attractions, I appreciated the advanced ticket purchasing and ease in skipping most lines.
Would recommend everything but the restaurant at the end. Most of us were not pleased with the selection or quality of food.
Still, 5 stars for the tour itself. The helicopter was priceless....quick (10 mins) but priceless!
