As I'm thinking of excursions, I'm also wondering about clothing to pack...
I understand that for many churches, knees and shoulders must be covered. The shoulders are easy and I'll just wear capris, but the knees might be more challenging for my husband and 3 sons on a hot Med day...
Although many males do, they will NOT wear capris!! (Blank stare from all 4 when I approached this option...)

:
If they wear shorts that are longer and cover their knees while standing, do you think that will do? Maybe they could wear them as "lowriders" to cover the knee caps?
I'd hate to get to somewhere like the Vatican and be turned away because of a few inches of fabric!!
Also - on a related topic, we have planned time in London and Paris on either end of our cruise and our suitcases will be very limited in space. I really don't think we'll have room to bring too many fancy clothes for the formal and semi-formal nights. Does anyone think this will be a big deal? I promise we'll look presentable!!
