Romanians travelling to small European republic (3,6)
I believe the answer is:
san marino
'small european republic' is the definition.
(I've seen this before)
'romanians travelling' is the wordplay.
'travelling' indicates an anagram.
'romanians' is an anagram of 'SAN MARINO'.
'to' is the link.
(Other definitions for san marino that I've seen before include "No marinas in this small Italian republic" , "Small European state" , "European microstate" , "Smallest European republic (24 sq miles)" , "Italian-speaking country" .)
