Thank you for the responses. It seems like the best thing to do would to be to visit the studio in person. I am a dancer, but have no experience with ballroom, which is why I have these questions. I've been wanting to start ballroom dancing for a couple years now, and am very eager and excited to start, so thanks again for the help!
Terence, I guess I assumed that I would do International, but I do not know what is offered at my local studios. I would be taking lessons as a single, which is why I think a chain would be best for me. I compared the prices of some of the independent studios, and it was about the same as my local Fred Astaire, but I do not know what Arthur Murray's prices are like, though I assume they would be similar. I am a female, and pretty young (a college student), so I'm thinking this all would factor into my decision. I would prefer to dance at a studio with people close to my age, though I realize that's not always the case with ballroom.
