We are smitten with Celebrity, no lie, and continue to be fans of this cruise line.
I won't go into details on embarkation/debarkation except to say it was the smoothest--on both ends-- we have ever experienced.
Last year the music around the pool area was so loud you couldn't hear yourself think, much less have a conversation. Celebrity listened to everyone's feedback, or else this cruise's demographics were different, but in any case the music was unobtrusive and very pleasant.
