I travel for work and want to take lessons

Have you thought about looking into an organization with dojos in a lot of locations? I may sound very biased in this (look at my style), but Seido karate has branches all over. They're independently owned, but the syllabus is the same. If you have one near you and near where you travel for work, it could work out well. You'd have to speak to both instructors to make sure they're ok with the logistics/terms. Seido is a very tight knit organization. Most instructors know each other pretty well, as they come to NYC from all over the world pretty regularly.

I'm sure there are other organizations like this. Kyokushin karate comes to mind. That organization is splintered, but the people I know in it are very accommodating.

Just throwing out suggestions. Neither system is for everyone, nor are either of them interchangeable. I don't know about TKD associations to suggest an organization to look into.
