Celebrity is a nice line, primarily skews older adults, school breaks and holidays not so much. Food is good to very good, Luminae is so very good. Service on Celebrity is IMO the standout best! Entertainment while not Broadway caliber, had always done what it is supposed to do, that is to entertain me and it almost always does. Depending on level of cabin you cruise in will of course have an impact on what you are offered. For celebrating your husband retirement, you should take a look at what the Retreat has to offer, it’s a very nice elevated experience. Whatever you decide, enjoy your cruise and happy retirement to your husband!
