Thanks for thoughts we are doing a disney cruise and flying in, thats why luggage between the four of us will be tight. I will using just one suitcase for our snorkle gear, three masks are optical so from past experience we bring our gear instead using rental stuff. I want be able to use things mutiple times, I don't think a PC will work in this situation. We have been on other cruises so I know how people dress. Would it be totally out of place to wear a waistcoat instead of a jacket?
