Having years of experience performing Segway Tours and training people, we can assure you that this event is very unlikely. We give every single one of tour participants a thorough hands-on training session (even those who have experienced Segway before), and we insist in training our guests until every single one of them feels comfortable and confident on using these unique devices. As such, in our experience it is really rare that anyone cannot master the Segway after completing the training routine. In any case if any of our guests feel stressed or particularly worried, or decide that this activity is not for them, we don’t force them to participate and give them a full refund.
