for a while now hotels have provided the option to opt out of fresh towels – but tonight i got to tokyo’s grand prince takanawa hotel, which has gone one step further: you can opt out of room cleaning altogether and you get an incentive in the form of $10 a day you can use to buy food and drinks during your stay. it makes sense for me, for them, and above all for sustainability. how many other services can be replaced with incentives to spare waste?
