Booking is convenient, and tickets can be purchased in advance. Payment is also easy. However, there's a limit on the number of people for group bookings. If you have a large group, you'll need to make multiple purchases, as it's not possible to complete it in a single order. After booking, your group will be assigned to different train cars, preventing you from traveling together. The interface for booking tickets could also be improved for better fluidity; it frequently jumps out when entering passenger information, requiring constant re-entry of details.
