Regarding the laundry bag you can fill up for $30 -- I read mixed messages about what are allowed in the bag. Some says only underwear, tees, PJ, etc., no pants or shirts. Other say no restriction (of course nothing fancy like dresses). Is there a rule? Shorts? Capris? I am trying to figure out how much to pack. I wish RCL has laundry room onboard. :(   Thanks!!!
