We were a group of 8 ladies on a 4 day trip to Krakow. We were approached by many people trying to sell us a tour and we thought it would be a fun way to see this beautiful place. the electric vehicles sit six comfortably but as there were eight of us, three of us wedged ourselves into the back seat which faced backwards and the other sat up front with the driver. Our driver was the problem. He appeared to think we were all more interested in him than in Krakow (we weren't) he wanted to tell us all about his past and how he was wanted by the mafia and kept having to move each time they caught up with him (a wild imagination if nothing else). He was from the UK I think from Manchester or somewhere and called Alex and he would not stop talking).
The tour started and if us three ladies had not been wedged in the back we would have been catterpalted out on several occasions as he drove over the kerbs and a few potholes.
The tour bus is fitted with a recording of the tour with speakers all over the bus so you can hear all about the places you are passing and learn the history of each part. However our driver kept turning it off so we could hear him talk about himself. I missed a lot of the tour because of this although as I was at the back, thankfully I couldn't hear his pathetic witterings. This The driver also tried to put his arm around my friend who was sat in the front seat (she didn't want to sit there but there was nowhere else to sit). The recording was turned on after we passed the Schindler factory and by then it was a dot in the background.
To summarise, it is a great trip, you can negotiate a good deal - the more of you there are the better the per person price. Get a guide who can ADD TO the pre-recorded guide but not talk over it and if you have a gut feeling about the driver then get a different bus - there are loads. With the right driver it is a trip worth doing.
