And another question is, when the tour company agreed to this, who exactly did that? Is there anything in writing about this, or was it just an oral statement on the phone by someone trying to sell two places on the tour? Reputable tour companies normally provide information on their website, or elsewhere, about the activity level and physical demands of a tour, with which guests are expected to be able to comply. Rick Steves, for example, is very specific about this for each of their tours. If a company doesn't do this, that is a red flag in itself. Does this tour company provide that info, and is their agreement about the scooter consistent with that? In case of any future dispute, such as (worst case scenario) the person being sent home from the tour -- which can happen, another thing typically in the terms and conditions is the company's right to do this if the guest cannot reasonably participate in the tour activities -- the stated terms are likely to control.
