oh, definitely get the advent isis hand pump. i used it everywhere - on a plane, train, in the car, at reststops, in dressing rooms, in the shower when i had clogged ducts, its great to have. its small and its quiet, i did it right at my window seat under a blanket. theres a bit of a learning curve, both putting it together and getting used to using it, so practice beforehand. bring a little bottle of dishwashing soap and you can wash it up in your hotel room or wherever with hot water. not only will it protect your supply, but it will relieve your discomfort and keep you from leaking. you can save the milk if you work it out, it comes in a little insulated bag, or you can pump and dump if you need to. it pumps right into the bottle, you can just switch the tops and feed her. have a great trip :)
