No, but if one wanted to have it set that way, why not?
It depends on the sofa. Do yourself a favor and let it be part of the adventure.
We always pack VERY light. We did a 7 day Western on the Enchantment, pre-stretch days, with legal airline carry on two each. I also had a RCCL tote bag as well with the swim stuff and the wife had a medium sized purse with her cosmetics.
We eat in the Windjammer so have no need to "wear once clothing".
