As per previous answer, but have you thought about packing your clothes already on your coat hangers, then when you come to unpack you only have to hang them up. The ones which are already in your cabin can then be removed and stored under the bed! I find this much easier.
This is often done by practiced cruisers but take the plastic coated wire ones or even just wire because they can increase your baggage weight. If you have badly creased items when you arrive get the bathroom steamy and hang some of the worst in there and most creases will drop out, or you can send them for a press. We can unpack in a very short space of time using the hanger method but there is always a problem of what to do with theirs. Well brought up Mr or Mrs Pellatt. regards. .... Neil.
Yes, just ask the Cabin Steward If you need more.
