Pack once, travel many

I hate packing more than any other part of a trip. In fact, if I could choose, I’d take a delayed flight over not having to pack. What if a company could do it for us? Travel bag-less to your destination, find your bag in the hotel room. Returning, just leave your bag in the room or check it in at the airport. Don’t even think about it until your next trip, where you’ll find it in your room again, everything washed, toiletries replaced if needed, maybe even a local guide, right there in your suitcase.
