It's really convenient to take the shuttle bus. It's a new nine-seater bus. The driver speaks very good Chinese and helps you buy tickets (38,000 NTD/person for 3 trips). However, there's no 3+1 discount like others have shared, so I only went there three times. However, it took almost the entire morning, and I returned to Hongdae at around 12 noon, which was just enough time for lunch before continuing my afternoon schedule.
