1 Lucia percovich #Coronavirus How do I process a voucher for future stay? they would like to change dates but dont know when 11 BrookAve Hi Lucia, For that they must deal with you directly. So you need their email and or phone number and vice versa. So you then simply email or SMS them a virtual voucher . Dont forget to set terms on it, expiry, value , or number of nights covered , max occupants etc.
