This was my 3rd trip to the big apple and my favourite because l had a change to visit some iconic areas of NYC.

Enjoyed the time. Easy to get on and off. Buses were always not very far apart to get on. We only got to take the downtown loop but it was very nice. Guide on final loop was very informative and easy to understand.
Maybe not possible but would have liked to have a stop at the Staten Island Ferry dock.
Plan to do uptown next time.

We enjoyed the ability to view many parts of NYC with a commentary on the sites. It's an easy way to visit several difference areas of NYC.

For such a big city felt there could be more stops instead of having you walk to various places at each stop. bus guides vary helpful and knowledgeable

We had a two day pass and were able to visit all the sights on our bucket list. The guides were very well informed and added to the trip except for two who thought they were in a comedy club. The evening tour was ruined by the guide who wasn't even aware that most of his audience was not American and didn't make any adjustments for them. Danny was a super host and we wished we had him on every tour. He was the only person to explain that different languages could be heard on different channels and he explained this in each language. So glad we at least had him once!

We love the Big Bus! We use it in every new city, where available. The guides give great commentary. The routes are the most convenient. Our biggest complaint was the lack of air conditioning on the busses. It was in the 90's in New York City! Definitely needed it. We took 4 different busses. Mark, who took us on the purple line to Brooklyn was great. Being from Brooklyn he passed a lot of information. We then took the Red line back to time square. The guide was very knowledgeable, but did have a superiority attitude. We were stopped at a red light and the sun was beating down so my brother-in-law decided to go downstairs and he was chastised repeatedly over the PA system for moving while the bus was in motion. Alas, the bus was NOT in motion when he went down the stairs. We understand the safety issue, but the berating was totally uncalled for....especially over the PA system.

The Hop on Hop off is a good way to get around Manhattan, but the Uptown route has been changed and it no longer serves as a good way to get around the Upper-side of central Park.
Considering the mad, mad traffic in NYC, the Hop on Hop off Red Route is a good way to get from Times Square area to Battery Park, 9/11 and Wall Street.

Not enough buses, bottom level of most buses has no Air Conditioning. Uptown tour was a flop because the Harlem Buses stopped at 3:00 pm didn't get to see Harlem. Not enough good Tour Guides.

I purchased 2 Classic Adult New York City Big Bus Tours Hop on Hop Off tickets through Viator....I still have all receipts and information for this transaction. The iternerary showed I purchased the 2 adult tickets for this tour $49.50 each for a total of $99 dollars.
When I selected the blue get ticket button on the itinerary it displayed the adult ticket to be scanned at the bus. The displayed ticket indicated 1 adult ticket ONLY. I called Viator immediately and spent more than 30 minutes on the phone with a woman from a foreign country call center.
She kept telling me she would take care of everything. She kept putting me on hold to get clarification from a supervisor. Then after a long time she told me... "Don't worry sir, Your ticket is the way all of them print out. Just show the tour bus guide the Itinerary and it will be fine".
Well, it was a LIE. I got to the tour bus in New York City and the man said No, I must scan 2 separate tickets and this is only 1. Yes, I see you have paid for 2, but you were only given 1 ticket....
You must purchase another ticket to ride the tour. So, I was forced to do so or we both could not take the Big Bus Tour....
Viator Lied....
Also s family got on the bus a stop or two later on the tour and told of having to purchase additional ticket because they too we not given all the tickets they had paid for over the phone.

I lost the money for 4 people.
They never esplain to me that there is a difference between classic and nigth tour.
