We are sailing on RC Freedom of the Seas-no self serve laundry. I was thinking of packing an extra duffle for laundry and will check that bag on the way home along with our other luggage, this will also make room for souvenirs in our luggage. Has anyone done this? Does anyone see a problem with doing this? It would just be clothes in the duffle so it won't matter if it gets smashed by everyone's luggage. Thoughts?
