This was our 21st cruise and our 4th on Celebrity, which has now become our favorite line.
Entertainment: the on-board entertainers were fine, but their shows were unfamiliar and uninspiring. We have seen some great on-board shows in the past (Rain, Chicago, Mama Mia), but these shows were among the poorest we've experienced aboard ship. Comedians were OK, but not memorable. Lots of variety in the daily activities with something for everyone, it seems.
Dining: Blu is great. Quiet, efficient, excellent food. But, we like to eat outside in the warm evening air, so most often we just ate dinner at the buffet so to take our meals on deck. We wish they would spiff up the outside seating for the evenings (tablecloths, candles) like they do on Azamara. With them, you're eating outside, so it's more casual, but it's like a real dining room.
Cabin 1642: great location; quiet; fantastic steward. Sitting area was next to the sliding door (some cabins have the bed right next to the balcony door). Very little drawer space, like everyone says, but we had plenty of room for our stuff for 7 days. Great bathroom. Very nice bathroom amenities.
