Mr. Hans Kim the tour leader, was amazing.. He was patient as we took photos and voluntarily took photos individually for me as I was unaccompanied. He even was more then kind to ask the rest of the tour participants, if it was okay to drop me off on the way back to Seoul as I was staying in Incheon overnight. He also voluntarily recommended sightseeing tips to me for my time left in Incheon.
He also made sure we were all comfortable and was very informative explaining background information to us. Incheon is beautiful, and I enjoyed seeing the sunset at Wolmi Island.
I recommend spending time in the China Town area if you can!
