Our tour guide, Ms. May, is awesome, very willing to help and has so many interesting information provided along the way. The falls and dam were spectacular, the tour is also reasonably priced. Only pity was the time constraint, each stop has no more than 20-30 minutes so it's hard to fully enjoy the scene for some ppl busy taking pictures.
We a family of seven were VERY pleased with our tour! Our guide did a wonderful job getting us place to place as his kept our attention focused on the next place of interest around the bend with his narrative!
Greyline tours is awesome. I needed the wheelchair accessible coach but it had a mechanical problem. When they couldn't get it fixed in time - they arranged for a RadioCab that was accessible and sent one of Greyline's drivers along as tour guide - what an awesome tour we had. I can't say enough about how Greyline handled this, and the tour was fantastic.
