We flew from Australia to Rome and had 3 days in Rome before catching the train to Civitavecchia. I had booked this online, it was cheap and easy and a definite alternative to a transfer or taxi. The walk from the station at Civitavecchia to the port entrance is not at all difficult, takes about 15 minutes and if you have wheels on your lugguage is no effort at all. You can even stop for refreshments along the way.
The boarding process was quick, easy and HAL staff managed it all with professionalism.
Our cabin was as expected, everything we needed with our own verandah and plenty of room. I had read a tip of taking a length of rope to allow the door to the verandah to be kept open. We improved on the suggestion and can now recommend a length of bricklayer's string to complete the job! It's great if you want a bit of fresh air in the cabin.
No problems at all with cabin
