Although Red Arrow is more than Greyhound, they have a superior experience. They offer a variety of cookies, cans of pop, bottled water, tea, and coffee. If you want a bottle of water though, act quick as they are usually gone halfway through the trip.
The aisles are wide and leather seats are comfortable and you don't have to worry if you have a seatmate because they have their a lot of space.
The wireless can on occassion be slow but it's great to be able to surf the internet or work without the worry of driving. If you don't have a laptop, bring your earphones as they show a movie.
For less than $70 one way, it's a great way to travel between Edmonton and Calgary and enjoy the amenities. They offer student and AMA discounts too!
