We took the Showtime Tours all-day bus trip to the South Rim of the Grand Canyon. We were not satisfied. The bus left the terminal over 1 hour late so he cut-back time allowed to be spent at the Canyon. Also, we got terrible seats in the back of the bus because the dispatcher told us to wait at the wrong gate. The bus driver gave no information about the Canyon. Luckily, I was there before and had much better tours!
