CONVENIENCE was the favorite part of our tour. We were picked up and delivered, safely, to the Gray Line Tours visitor center on Niagara Falls Blvd. No traffic hassles, no parking fees, and no waiting in line to purchase tickets. We saw and learned more about the Niagara River Gorge than we could have imagined. Ross, our tour guide, was courteous, very friendly, and had a wealth of knowledge...not to mention his choice for our lunch stop...the Dicamillo Bakery was great.
