Make your way to a central location in downtown Houston to board an open-top bus for a guided tour of the city. See Hermann Park, City Hall, and the Museum District, while listening to recorded commentary that's full of local facts and stories.
Next, continue by coach to the Space Center Houston, where scientists and astronauts launch rockets and space programs for NASA. There's also a tram tour of the Johnson Space Center included. Watch NASA staff at work, check out the former and current mission control centers, and see the Saturn V rocket, one of the most powerful rockets ever built.
Don't miss the space shuttle replica, Apollo 17, and the International Space Station Gallery's interactive exhibits that explore life on board.
Following your free time at the Space Center Houston, meet back up with your driver for the return trip to downtown Houston.
