Great tour for the price. My favorite tour was the Uptown portion as well as the Night Tour.
Cons: Didn't say Brooklyn and Bronx tours were only once a day. Also, the bike rental ended up being more than advertised so we didn't even do them.
The bus had no air conditioning. It was very uncomfortable on the inside and too hot to sit outside. It made for me and my family a very uncomfortable situation.
This tour was great value however the buses are not as frequent as the Big Bus or City Sightseeing buses and the routes not as comprehensive. Having said that once on the bus the experience was very good.
