For information on Tour Confirmation Vouchers, see the below article.
Vouchers are not mandatory but are often requested or expected by passengers as it adds additional peace of mind that their booking is confirmed as per their request and gives them something physical with detailed documentation to refer to on the first day of their tour.
If you do not offer vouchers, don't worry, you can simply click past this when confirming the booking.
But what is important is ensuring that the passenger is aware of what documents they will and won't receive at the time of booking. It is one of our most commonly asked questions from passengers post-booking and can often cause concern for passengers who don't hear back quickly enough. Sending this information out as part of your booking response every time, makes you appear professional and trustworthy, and it's more likely that passengers will recommend you to friends.
