Honestly, I'm not sure what everyone is raving about. It was a lovely way to see the city but the driver spend the entire time making duck jokes, and yes I get that duck jokes are the gimmick but I thought there would be a little bit more information on the city. He would point out a building or statue and mention the name but that was about all the info you got before he started quacking again. It also only takes a quick route through downtown then spins up by the stadiums on water. I thought we would see more.
Our seats were REALLY uncomfortable. We were in the back and the space was not long enough for our legs. We shared the duck mobile with a large (Somewhat pushy) elderly group who were not interested in sharing with us or the nice young couple who were there with their toddler. They cut in line, tried to sit in all the window seats and It was a battle just to get them to move around so we could sit together.
All in all I wouldn't recommend it for grow ups. Fun if you have kids (or are pushy spoiled old folks who act like kids!).
