I did think about phoning them to ask, but I can only find the Assist Number, don't seem to have a 'general enquiries' number.
The AA want £102 to cover the Disco and trailer for 2 weeks - but they specifically state that if a replacement vehicle is required (whilst you are in Europe), they will not be able to supply one with a tow bar :? , which sort of makes spending the 100 beer tokens pointless - unless of course it's something that can be fixed, rather than needing recovery to the UK.
