I've done T/As and T/Ps on both lines many times. I agree that you'll enjoy Oceania. And also that it might be best for your first O cruise to be on one of the "larger" ships..not that they are that large! Celebrity suite prices have gone through the roof. I love to play Trivia, Mah Jongg and go to the various lectures during the day. Or just read my book up in Horizons with the fabulous views. I can be as busy or laid back as I choose. Please let us know what you decide!
