Hi John,
We did our very first cruise in June 2005, on Oceana. There were 2 adults and 2 children and we went round the Med. I did'nt really do much research prior to going, but a few weeks before we went I read a couple of reviews (some on here) and they were extremely mixed!!
We loved it so much that we went again on Oceana last April 2007 and bought my parents along too, whom also had not cruised before.
She is a family friendly ship. and I would say there is a good mix of ages. We loved the whole experience. We chose on both holidays to take formal dining with the 2nd sitting option.
A ships newsletter was delivered to our cabin each evening outlining the dress code for the next evening and also the events that would take place during the day.
We had on our weeks cruise 2 formal, 2 informal and 3 casual. On both formal nights majority of gentleman wore tuxedos (dj's) and the ladies long elaborate dresses, everyone looked gorgeous, even the children get dressed up too!!
On informal night, suits were worn by the men, and ladies wore cocktail dresses or trousers and sparkly tops. Casual night saw people dressed in trousers and polo shirts for men, and skirts and tops for ladies.
During the day weather dependant, shorts, jeans etc around.
There are a few child free zones on board so you can escape!!
Plenty to do, we loved the staff and the service. We stayed the first time in a mini suite (lovely), second cruise was an outside with balcony .... if you can opt for a balcony then do so.
Food was plentiful, good choice (in our opinion).
We are fairly laid back when we holiday, so we don't let silly little mishaps spoil our time, but you will ALWAYS get those who love to complain.
I thoroughly recommend cruising whatever your age, and loved Oceana.
We are off on Ventura next week .... parent's coming again too!!
Hope this helps
