Our group of 8 took a private Seoul half day tour. Denny (Kun-yong) was a terrific guide. For many of us, it was our first visit to Seoul so we wanted to see some of the major sights of Seoul city and we were able to do this with the limited time. Denny's English was good, his insight and information on the areas we visited was terrific and he took note of the time allocated so was able to fit everything in. I would recommend and would certainly use Denny again again on my next visit to Seoul.
