We had OH's passport pinched from the unlocked-overnight car, the idiot! Phoned the Passport Office, told to take relevant docs to Passport Office for replacement. Problem was all the relevant docs were at home, in Germany, took a while to explain that we couldn't 'deal' with it from Germany as we couldn't get back there. Luckily MOD, his boss at the time, had all our details and they faxed them to Liverpool office. We now always have a number of photo-copies of the passports when we travel.
Hope everything goes well for you daughter's trip Pasta.
