We have only started cruising this year, this is our third cruise and all on the same ship as it is based out of Brisbane which is closest to us.
We have done two 7 day cruises Feb and Aug 12 and one 12 day cruise in Oct.
Where can I start, check in can be a bit chaotic for newcomers, however that is ok once you are in line it goes along smoothly. Unlike air travel I recommend to arrive four hours prior to departure, that allows you to stow your bags, enjoy lunch and explore the ship before the mandatory emergency drill exercise.
Quiet and good view, close to aft and sufficient room to store everything.
