Had to go on a business trip to Las Vegas, and figured we wouldn't get a chance to get that close to the Grand Canyon for a long while, so we booked the trip at a great price through Expedia. Pickup was early, but we were so excited we didn't mind. Wally was a terrific tour guide, very knowledgable and friendly, he hardly stopped talking the whole way to the Canyon, except to show a few videos. We were glad for the stop at the Hoover Dam, a quaint Route 66 town, and one other bathroom/leg stretch break. We thought we would have 3 hours at the canyon, but by the time we were dropped off at the end point and took the shuttle bus all the way to the start point, we only had about 90 minutes left to walk the almost 3-mile South Rim. Certainly not enough time for such a spectacular location. But hey, unless we planned a two-day excursion, this was the best we could get. The ride back was a tough one. With only one stop along the way, there was nothing to see in the dark so we watched two Vegas-themed movies on the little bus screens - not ones I would have chosen, but better than blank screens. By the time we were dropped off at our hotel, we were exhausted. All in all, I would give Wally 5 out of 5, the canyon itself 5 out of 5, the ride there 4.5, and the ride back a 3.
