This was our second cruise, having last year been on a 7 night cruise on the Azura.
Although the Oceana is quite a bit smaller, we didn't find the range of facilities inferior and, indeed, found some, especially the buffet restaurant, better. It's hard to compare cabins as last year we had a suite and this year a balcony cabin. We found the space adequate. We were very happy with the location of our cabin, being on the Lido Deck and so very close to pools and sunbeds and only down some steps from the buffet restaurant.
Club dining was excellent regarding both quality of food and service. The only disappointing dining experience was when we went to Cafe du Jardin, Marco-Pierre White Italian restaurant. Service was slow and the waiters were quite unenthusiastic about everything. Food was OK but a limited choice and not worth the extra cost.
Last year we were part of a large family group so didn't get involved in the on-board activities. This year, however, in an adult foursome, we visited the theatre a couple of times and played bingo on a wet day at sea. We were impressed by the organisation and quality of these activities.
We chose this cruise for the length and timing of it rather than the itinerary. The first stop, Vigo, was very disappointing, a drab port, especially on a Sunday. Lisbon was interesting: used the hop-on hop-off bus which was fine for seeing the city but became a bit of a drag when it went further out from the centre. Oporto was the highlight of our shore visits, a quaint waterfront and very interesting port-wine cellars. We visited Guernsey for the second year and again found a hire car a good, cheap way of seeing the island. St Peter Port doesn't have any more charm than most mainland seaside towns and we wouldn't choose to visit Guernsey again.
We shall definitely book another cruise within the next couple of years, almost certainly with P & O and would be very happy to go on the Oceana again.
