Our tour guide, Miller, was EXCELLENT!!!!
I would take this tour again, except that the time at the top was so short. There has to be a better option. Find a geek who can set up an algorithm to allow passengers to chose their return time. I WOULD'VE PAID EXTRA $$$ for more time at the top.
The ride up was FUN!!! Would give a full 5 stars just for the excellent service at the counter inside-so friendly & accommodating, and our amazing tour guide, a natural teacher of geology, botany, history, geography, photography, and so much more!
SKIP THE DONUTS!!! Getting through the line was miserable. Paid for 2 coffees and there was barely enough coffee in the pot for one cup. After 5 minutes, I went to the back kitchen where staff was chitchatting and asked for more coffee. Waited a few minutes and left. Will write a separate review of the gift shop/restaurant.
Decided to pass on the coffee and get outside to see the top of the mountain for our remaining five minutes.
No time to take a picture!
The bathroom wait at the depot was frustrating for our party of five, and the rest of the people getting ready to depart.
Were it not for the excellent guide and the lovely man at the counter, I would give Grayline 1 star on this for hurrying their passengers through like cattle.
