We had the 11 day southern/western Caribbean cruise at the end of January. Weather was good except during the last sea day when it was rainy and coldish. It was very sunny and hot down in all ports we stopped in. Formal evenings were on the second evening (before Grand Cayman) and on second to last evening (after Mexico). People on the whole were quite senior (we are on our late 40's) but there were quite a lot of younger travellers as well, but not kids though. Service in the ship is really friendly and excellent. Almost everyone is always smiling!
We also had a CC Roll Call meet and greet (arranged by Celebrity) on the second day where we met each other and ship's officers, but we didn't do anything beyond that with those people. Most of them had common, privately arranged, excursions together on later port days.
Summary:
Large corner cabin, very quiet location, windy balcony. Lots of storage space.
