You are only limited as to how many you can carry, pull, push etc. There is limited storage in the cabins, but I have seen couples, no kids, with 2 29 inch spinners, 2 21 inch roll aboards, 2 huge duffels, 2 tote bag sized bags, her big purse, and at least 2 other bags, for a 3 night cruise. I could give them the benefit of the dout and maybe they did a B2B, but come on, there are laundry facilities on boards, you can send stuff out to be washed. Maybe they were going to WDW after? Anyway, they were in the "we will take our bags off ourselves" state of mind. Holy pugoli, not an easy thing by the looks. If I had that much, I would let the room people take most of it the last night and collect it in the baggage area with a porter and a cart.
