We had to wait in line for 1 hr 35 mins to buy the tickets. We waited for another 30 mins to get on the boat. The ordeal was totally worth it: the boat trip was awesome!! The view of the Falls from the river was breathtaking.

The waste of time was completely on us: we went there too late, and without tickets. My advice is: purchase your tickets on line--or the day before since they are good for three days--and get there early, say before 9am.
