Tips for first-timers
The number of $1 fares available for each destination is limited. Don't wait. Book a few weeks in advance. The offer is ongoing.
When booking online, look for the orange "E" designating Express buses.
Choose your seat as you board. Because of the way the air-conditioning is vented, window seats tend to be colder.
A 30-day unlimited travel pass is $461, but for $100 more, you can get a 60-day pass.
The Express buses have a restroom in the back, but as with airplanes, it's best not to sit near them.
