We are a couple in our 50's and have cruised about 10 times. We have cruised on the P&O, Royal Carribean, Princess and Carnival lines. We had never tried Celebrity but are now converted.
We embarked in Auckland, dropping our luggage at 11 a.m. but upon seeing the line went away for some sightseeing and came back at 3.30pm. We breezed through all the paperwork and were aboard in about 10 minutes, picking up a complimentary drink on the way through.
Our cabin was 6140 and we had our first ever balcony. I don't know how we will ever go back to a window only cabin next time. The cabin was a great size with a king sized bed with plenty of room to walk around it. The lounge was good and the flat screen can be swivelled to watch TV in bed or on the lounge.
