I would really give some serious consideration to checking the prices of laundry services and having it done for you. I ended up unexpectedly needing to get a couple things laundered later on while on our last cruise and I was really surprised how affordable it was. One take away from my last cruise is I will plan on packing a little less and use the laundry services more next time! Everything was super clean and pressed perfectly! Never had my shorts pressed before, very nice!
My thinking is - we're paying a lot to cruise and I don't want to spend any time on things like this. When I break down how much I'm paying per day or per hour to be on the cruise I hate the idea of spending x number of hours doing laundry.
Doesn't answer your question, lol. Just my $0.02
