Yes, you should learn but don't just buy into a dance company's name. Research the best option in your area with the best teachers. Maybe it's Arthur Murray and probably you'll get a better deal and a better instructor at an independent studio. They won't make you learn dances and steps you don't care about as a part of their teaching syllabus.

Don't get talked into a slick plan and don't sign a contract. If your instructor can't make it worth your while every day without a leash to keep you coming in then why are you paying them at all?
