We chose to go on Britannia as it's the onlt P&O ship we haven't been on.
After reading some reviews we were a bit unsure of what to expect, alot of people didn't seem to like Britannia, but we needn't have worried it was amazing, in fact my wife & i both said it is now our favourite ship.
The balcony cabin was excellent loads of room & very modern, getting around the ship was extremely easy also in the reviews quite a few people said navigating the ship was a problem for them but i can't understand why, we found it to be very easy. I thought the sheer size of the ship & the amount of passengers would be a problem, for seating at shows or the Costa places but we never had a bad experience at all seating wise.
First time in a balcony very impressed will probably go for balconies all the time now, The room was very big & the shower was very powerful we couldn't really fault anything about the room
Very "green" place not what we expected the port area was very very busy
Stavanger was a beautiful place with lot's of traditional built houses
Olden was extremely beautiful with lots of great scenic walks
