Not a heck of a lot in each bag. Try rolling the soiled clothing and squeezing it in-we've gotten so good that our one dirty bag always comes back in two clean bags. EACH Platinum cruiser gets 2-3 bags, depending on the length of the trip. Make sure you put your folio number on 2 or 3 bags and your "roomie's" folio number on the others. Carnival just started something new with Platinum, though. Don't be upset to see a $15 charge for the bag--followed by a $15 credit, this is their way of counting your bags.
