We did a cruise shore excursion out of Greenock. Our guide/driver was Frank. We honestly can’t imagine a better tour. He took us to beautiful places some of which were pretty out of the way. He really has fun in his job and it’s infectious. We took some tours through our ship in other ports. They were at least twice as expensive as Busy Bus and nowhere near as good. I’m going to tell anyone I encounter who is vacationing in the UK to check out Busy Bus!
