What a great introduction to Glasgow! The full tour is about 90 minutes which helped set our bearings and gave us things to consider visiting in more detail. The guide had a wonderfully heavy and enchanting Scottish accent, though at times my ears and brain found it a bit difficult to comprehend. It would help if the bus had more speakers up top, and it would help even more if the speaker volume was turned up. The tour includes a drive through many lovely tree-lined streets, so take heed and avoid getting slapped in the face by tree branches if you're up top on the left side of the bus.
