My inlaws cruised with P&O last year (Norwegian Fjords) on Oceana and loved it. After discussion we decided to take the plunge and take our first cruise, this time to the Baltic states. After pricing up for two cabins, one inside one outside, (we needed a cabin for our teenage daughter so it was worth shopping around to see who had the best deal on the single supplement), we booked.
We arrived at Southampton early (which I would advise to avoid any traffic issues and too many people arriving at once), car was taken away promptly and efficiently, waited to be checked in which was painless and quick (cards are created there and then with your photos/name/cabin number which are needed for purchases and leaving/arriving back on ship at the ports), then waited in lounge (about 20 mins), then we were called.
Boarding the ship took our breath away. Having never cruised before I was amazed at how big the ship was. After a short walk around we headed to the aft of deck 12 to get a drink and wait - one for the cabin to be ready and the second for the ship to leave. At 6pm the band played and Oriana set sail.
C140/C144 outside. C142 inside. Fairly small cabin if beds made in queen bed configuration if there are two people sharing. Bathroom tiny but bath/shower more than adequate. Not much room for legs when sitting on toilet. Location at front of ship so can be quite a walk to rear or any entertainment at rear of ship.
