I don't do spinning things very well, but I loved this ride (at least 6 times!) as said above, you control the spin. We ended up riding me and DH in one car and the two kids in another! Unfortunately my DS aged 6 at the time whooped all our butts!
As for Men in Black, after assurances from DH and DD9 that it didnt spin much on their 'test' ride, went on and never stopped spinning for the entire ride!! They said it was because I was a rubbish shot!
