Embarkation was laboured and disorganized - we queued for ages at check- in - we were advised that there were too many people on the gangway - when we got to the gangway we were penned in a glass overbridge for at least twenty minutes in the heat of the midday sun. Luggage also took a very long time to be delivered to our stateroom - in fact we had to attend dinner in the clothes we traveled in. Not a great start.
Ports of Call - with the exception of Mykonos and Split were very good.
The mercenary approach Celebrity take with their customers all but spoils the cruise experience. As others have said Celebrity are in your face to buy tours, treatments etc. they also are not above misleading people into purchasing stuff on the basis of savings which don't materialize. A couple of examples of which was an offer of a reduction of $30 on two spa treatments bought on embarkation day, what they failed to tell you was that one of the treatments had to be taken on embarkation day. It is worth "standing your ground" and demanding a reduction of $30 (plus the 15% gratuity) - I did and accused them of misselling - they then changed their attitude and credited my account.
The Cabin design could have been better the closet door collided with the bathroom door if both in use at the same time. Sliding closet doors might be the answer.
