We did the trip twice last year Corfu Montenegro Croatia and this year Montenegro Corfu. We did check out the second time we left Greece as we were new we would be away for a season. When I arrived back this March we went over to the port and had the book stamped but they were not really interested.

One word of warning. Once we sailed direct to Dubrovnik from Montenegro due to the prevailing winds. We were in trouble with the authorities they said we should have stopped at Cavtat and were going to fine us but quick thinking me said we came direct from Italy and out side their territorial waters it seemed to satisfy them.
