We got the 8 hour tour and it was great. They picked us up at the hotel and were very punctual, meeting us at the appointed time. The guide was very easy to understand and spoke English very well. The van that was used to take us around Busan was very nice and spacious for 4 people. An extra person could have easily fit in and still would have been comfortable. The guide took us to all the places that we were most interested in and always accompanied us through the sites. We didn't really interact with the driver at all, but he was friendly and drove the van smoothly. Some taxi drivers that we encountered were very heavy on the gas and break which made for a nauseous experience, but not our guide driver. Great tour and my group would definitely book through Get Your Guide in the future.
