If you take a bus to Epcot, you will get off at the front entrance to the park. The skyliner is at the opposite end, or the International Gateway entrance, which is also where Beach Club is located. If you are going to Cape May, the easiest thing would be to drive, or take an Uber. You could bus to Hollywood Studios, and take the skyliner from there, but honestly, it's not very direct to do it that way. You would get off at the International Gateway entrance, and then walk to the Beach Club.
