Don't waste your time, there are plenty of other bus companies with cheaper prices and infinitely better service.
Purchased two tickets together but there isn't assigned seating so we couldn't sit together.
The bus smelt like feet and urine and the windows don't open, so you're sitting for hours feeling sick on a disgusting bus.
The attendants didn't call out the buses while we were waiting or even direct us to the right place so we almost missed the bus.
Just an all around miserable experience.
