Just confirming what others have said about San Giorgio hotel. DO NOT book with them. They will absolutely confirm your reservations and go as far as sending specials for their wine and cheese get together. Then at the last minute they cancel your reservation.
BEWARE! HOTEL SAN GIORGIO . We reserved and paid in full for this hotel over 7 months ago. Today we received an email stating that they over booked the rooms and they no longer could accommodate us. We are a large group from different parts of the country and different countries all meeting up in Civitavecchia. Five of our six rooms were cancelled. They did offer to put us up in a 3 star hotel (much less than what we paid for this 4 star hotel) or refund our money. Well, being as we have only a week before our cruise, alternate accommodations are not to be found. Also review this hotel on Trip Advisor. You will find multiple reviews of the same thing happening.
