We went in April 2008 on Sea Princess and enjoyed the cruise a lot. We both took too much luggage so I no how you feel, but lets face it you want the correct attire. Good little tip take various size cases so they fit inside one another. Yes store them under the bed.
You should be able to put them under your bed.
Just make sure you don't burn your nose on the light fitting!!
All luggage has to be stored in your cabin, there's usually a small area for this (also under the bed if cases are the right size). Good luck, the wife could always sleep in one of the cases!!!
Thanks for the best laugh Iv'e had in ages.Sounds just like me.
