We've talked before about avoiding packing hassle by shipping diapers to your travel destination, but good friend and frequent traveler Cory Doctorow (of BoingBoing and Craphound fame) took it a big step further with great results:
Don't suppose I'm the first to come up with this, but I've had amazing travel success pre-ordering baby supplies (diapers, formula, powder, wipes, organic food — anything bulky and/or hard to come by at a 7-11) from Amazon and drop-shipping them to our hotel in advance. We don't have to fill a suitcase with consumables, and Amazon beats grocery-store prices in most cases (especially for us, since this stuff is always lots more expensive in the UK).
After our wedding we spent a couple days in Houston en route to Honduras. Rather than bring a month's worth of baby stuff to Toronto, shlepping it to Houston, and thence to Honduras, we ordered EVERYTHING – — formula, rice cereal, food in jars, diapers, powder, wipes, cream, pop-up crib, baby bathing suit, sunscreen, etc etc — from Amazon (along with a $10 wheeled duffel-bag to put it all in!) and had it shipped straight to Houston. It worked INCREDIBLY well, and since we left a suitcase worth of wedding-clothes, etc, in Toronto after the wedding, we were able to go very light indeed.
You know the best part? They left all of the packaging at the hotel (along with a generous tip) and it was taken away by housekeeping.
