People will be happy to have you in a dojo if you are polite. Aikido is difficult because the moves are very subtle and requires you re-learn how to use your body. I liked it because I'm n ot fast, so I could spend a lot of time conceptualizing movement.

As far as Karate styles, just join a dojo. If you like it, don't worry about style. You'll just get confused. You'll still learn self defense.
