P & O Oceana is way better than NCL. Although NCL are OK you feel far more valued with P & O and the service and food is better.
Do you mean Oceana the P&O ship or Oceania the cruise line? In either case NCL would go to the bottom of the pile IMO.
I mean P&O Oceana, i do realise that NCL is alot more relaxed than Oceana have you cruised on this ship? what didn't you like about it? also i am wondering about P&O Ventura, the reason is i would like to try different cruise lines, i am unable to fly so have to depart from UK so don't have too much choice for a med cruise.
