Take it by the positive side.
If you have only your handbag:
No air weight limits. No missing luggage risk. No need to look for luggage as you disembark.
More space for souvenirs.
No questions about dress code.
But in this case....
... no need to post topics as "Can husband wear jeans?" in Carnival chat.
... no Karrie to get mad.
... no Mr. October to post photographs showing what "his hope" would be.
... no view of Chef Ken's Minneapolis new coffee shop.
Wait a minute: does all this belong to THE POSITIVE SIDE ?
Better traditional clothed cruises ...
