Just a suggestion - pick up a package of those Purex 3 in 1 laundry sheets (the kind you put in the washer and transfer to the dryer) - they are expensive for every day laundry but GREAT for traveling - you can put a few in a ziploc and they weigh nothing - and it's far less expensive than buying it there and there's no risk of spillage in your luggage!
