Snaptravel affords no leeway in refunding cancellations, even under dire circumstances (physical incapacitation, covid-19 contraction). If you miss their 6 day window, you're SOL. Regardless of legal terms in the contract; these are unparalleled times, and reasonable cases should be judged on the basis of their reasonableness and should be afforded decency and charity to a company's customer base. Snaptravel is clearly disinterested in preserving their reputation and doing the "right thing". Don't waste your time with the people. Reserve with a competitor who has a heart (and working brain, for that matter).
