BOLT BUS is a spin off from its parent company Grey Hound Bus.
Prices fluctuate but its from $1 to about $15 to Philidelphia one way. Supposedly the earlier you reserve, the cheaper it is. No telephone numbers to contact, everything was done online. There is walkup fares at the pickup curbside but its most likely more than what people reserved online. Once you purchased at their web site, they sent you confirmation to your cellular phone.
The buses they use have more leg room & clean. The best part is they have AC outlet on each row of the seats so you can charge your electrical appliances while you are on the bus. They also said they got free wifi on the bus but that one was not tested by me.
I find the bus clean and comfortable. If its always on time like the trip I have, I will use it more in the future. FYI the company charge 50 cents for booking fee.
I paid $10 from NYC to Philly & then $12 back from Philly to NYC. I see that if I buy one month in advance, I would have got some $1 one way ticket.
Philadelphia has many historic and cultural places to visit, so why not do it by tour bus? The Big Bus departs on the Northwest Corner of 5th & Market street daily, stopping at 20 different sights.
Historic walks depart from the terminal at 5th & Market and are $10 for adults and seniors and $8 for children.
Hours are 9:30-5:30 p.m. April-November; 10 am-4 pm December- March each day. All day inclusive tour costs are $27.00 for adults; $25.00 for seniors; $10 for children 4-12. Tickets can be purchased at The Independence Visitor's Center (6th & Market St.) or Online. All day inclusive tickets provide on/off privileges.
I used the Chinatown bus from Boston-NY continued with NY-Philadelphia. You can go to 135 Canal Street or Broadway Street, NY to take this bus. The cost is 12-15 usd for a one way trip from NY-Philadelphia.
One of the thing you notice right away when you walk in downtown Philadelphia are the many different "Hop On, Hop Off" buses/trolleys. They all take you to some 18-19 stops around the city.
Since we were only in Philadelphia for a weekend, we decided to take one of these buses and ultimately chose the Big Bus Company for one reason: it is the only one with outside seats.
However, chance had it that both of the buses we hopped on had deficient microphones. On the first one, our tour guide bravely walked around the top floor while bellowing out Philly facts (falling once and getting hit in the head by the branches of the trees on Antiques Row); on the second, our guide simply stayed inside, so people sitting outside could not hear what he was saying.
With the Big Bus Company, you pay for the novelty of riding a double-decker bus. If you don't intend to take photos, the Philadelphia Trolley is some $2-3 cheaper. Also, Phlash is by far the cheapest option (not to mention that buses come by every 12 minutes instead of every half-hour), but I think that's because there is no guide on board. If someone could fill me in on that, I would appreciate it.
