Let me start by saying you should avoid this business at all costs! The crummy operation has so many faults it's almost difficult to list them all. But I will start;
First of all the app is a total piece of garbage. It doesn't give you a real time position of the buses and when changes are made to the pickup spots it's not registering.
The audio tour is absolutely horrendous! It's read by two childish voices that have no sense of history or drama. It's infantile and sophomoric, and very condescending to the listeners. Most of it is trashy music and they're are long pauses without information being given. As we went by famous buildings, there was no description given about most of them.
Trying to get help from the street hawkers was pretty much useless. They have heavy accents and most are polite but they just want to sell you a package. We walked around Times Square 8 to 10 blocks going from one stop to another and back again, these people hadn't a clue.. Internal communication between the vendors is non-existent at best, and horrible from central office.
Seats on the bus are hard plastic and Ill formed, it's difficult to keep your butt to the back of the seat without sliding out.
The good thing about having a broken audio port is that I couldn't get the volume any higher which is a blessing because of the chattering and all the blah blah blah that is on the audio track I couldn't take it any higher.
I suppose I could go on, but why it beat a dead horse. That's what this Hop on Hop off is, a dead horse!
