For anybody that hasn't been and is anyway into retro rally cars this is a must. Can do the trip quite cheap too.
Unlikely to ever see as many Group A Imprezas in the one place again.
Closest airport is Bologna that fly's from Dublin.
After that you have Pisa, Venice, Milan and Verona.
I'm going out on the Verona one Thursday and back the Sunday.
Lots of hotels then in Rimini as anything in San Marino be booked out and its limited anyway.
