Would have preferred at least equal attention to history as there was emphasis on skyscrapers. Please publish expected intervals between buses for us who do hop off wanting to hop back on. We waited a full hour plus for a bus and didn’t see any pass on our approach to the marked stop.

Need better coordination, as we wasted time waiting for the new voucher , as the original voucher sent by email did not work or scan wasted one hour , we have large group of 40 pax stranded i the cold waiting for the new voucher

Good services but could be better with more frequency

Good experience. Helpful drivers.

Use a digital pass to make it easy to book. It's very convenient to use on a smart phone. The staff was very friendly and personable. They told us about some of the places we might like and how the tour worked. Thank you for having a guide who could speak English! The wait time at the stops was very short. Commentary was good. It gave enough information to get a good sense of Frankfurt.

Because we had fun, even the staff was very friendly and helpful. Amazing! I'll do it again in a heartbeat!
