How long have you been in the UK? If it's over 6 months you can't get a Eurorail pass, BUT, you can get an Inter-Rail pass which is essentially the same thing, but I think better!
It was great becasue we got free bookings, went up into Switzerland for fuck all, went from Rome to SOrrento, back to Rome, then to Florence, then to Switzerland, thento Nice, then Bordeaux, Chinon, Paris, Rreims, Paris, but that's three different zones.
Check it out, I think they are well worth the money, we wish we made it to the Cenque Terre region, my fault for missing that when we went.
