you tow it--the steward will stow it......
.but seriously, what are you thinking of bringing? or, are you planning the 112 day world cruise.......the airlines are pretty picky about charging for the over 50 pound,2 bag limit . also, at the airport the porters are few and far between, but we've always had good porter service when exiting the ship.......not so good when arriving. we typically are unceremoniously dumped at the curb at the terminal then the 4 of us strugggle to pull our own weight in bags into the terminal.........(well not quite that much baggage but it seems like it when we are hauling it in and out of hotels, limos, cabs, airport security, and I am packing and repacking it!!)
Just wondering..How many times a day do you plan to change?
I know of a couple who traveled in Europe with 2 carry on luggage bags for 2 weeks.
They wore things 2 and 3 times, and changed their under garments every other day.
Fine if you don't sweat a lot...lol
