we are looking for advice before we travel to cusco, sacred valley & machu picchu this fall. one tour operator has asked us for passport info--they say it's in order to make reservations for the perurail to machu picchu. is this necessary? we are wary of identity theft problems.
also, the operator is asking for an 80% deposit but does not take credit cards, just western union or paypal or wire transfer to their bank account. should we worry?
thanks in advance for your help.
