Fantastic time with Gary and so grateful he helped pre-arrange tickets for us. We went to Eobi Ice Valley, Nami Island, Garden of morning calm and the railway. Had a fantastic lunch
Kevin's professional and enthusiastic leadership made our day happy and fulfilling, even though the weather was very cold!
