I have used the Hop-On Hop-Off buses in the past and have a great experience each time. This time was different. The bus driver would make random stops that were not included on the route map as scheduled stops. These stops would be last approximately 20mins with no explanation as to why the driver had stopped. At one stop for Rosenborg, the driver stopped two streets away! We had to walk to 10 minutes to get the actual palace.
Later that day my friend and I were still on the bus. We were sitting up top on the second level. There was another couple sitting ahead of us. All of a sudden, the driver stopped at a non-designated location, stopped the bus, got off, locked up and walked away without advising anyone! I went downstairs and all the doors were locked. We had no way of getting off the bus! My friend called an emergency number that was listed on wall but was forwarded to a technical school. A few minutes later the driver came back to move the bus to the over night parking garage and got mad at us for being on the bus. The driver did not announce that the tour was over or that this was the last stop. He didn’t check the bus either before locking up for the night! It was a horrible experience and not a great way to start our vacation.
