One place to look at is Kukkiwon headquarters.

they schedule entire taekwondo vacations. Talk to a travel agent for help. You can tour taekwondo museums and train at the Kukkiwon headquarters. I have been looking into it some myself and some of my students
You don't need any info. You research for some TKD clubs in Korea, pack your bags, make sure you have money and you go.
I'm interested in actually going to korea and learning more about taekwondo. any info on how i can get started or just any info on how to check?
