We were originally booked by a different operator on a large boat out of the main Bergen harbor, but they had a fire on board and canceled us the evening before. I went to Tripadviser when the hotel couldn't help us book anything, and went with the full private excursion. I received a call later directly from Bjorn saying that the full day wasn't possible because the lunch arrangements couldn't be managed, but we would be able to have the half-day excursion and would be refunded the difference. As mentioned in other reviews, the pickup and 1 hour travel worked well, the drop off with the walk to the train was fine, but the train back to Bergen was delayed by an hour due to mechanical issues, obviously not an expected occurrence. Warning - no available bathroom facilities at the train station!
The tour itself was the experience we wanted, beautiful views and tons of photos taken by Bjorn of us. As mentioned elsewhere, you should be aware that Bjorn is truly a guide, not just a captain. I will remember many of the stories told on this trip, fortunately my wife and I are not easily offended and we shared many laughs.
The overall review is that if you want an adventure and many stories to tell, the Zodiac is the way to go. We were lucky to be able to go given the last-minute booking, but the efforts made on our behalf were appreciated.
