Was looking forward to the Houston city tour with the Space Centre transport included. In reality we were driven around the downtown skyscrapers, theatre & graffiti park. The tour audio was from a recording & several times brought up the wrong city info. Not very informative, nothing about the artists, nothing about what makes Houston tick, no stops for photos at any points of interst just constant driving. We swapped to a smaller van for transportation to the space museum no pre-info on how necessary it was to download the NASA app to pre-book the trolley tours. Our trolley tour was delayed & was 20mins out, leaving us 4 mins late to catch the minibus. They left without us, the was no contact number or email that worked. Took us an hour & half to get back into town.
